Hamiltonian-Based Control Approach with Pendulum Application

R. C. Pozna Á Ballagi Radu Emil Precup

Publication Name: Saci 2024 18th IEEE International Symposium on Applied Computational Intelligence and Informatics Proceedings

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 593-598

Description:

The paper proposes a design method dedicated to control systems, which use a certain energy function (surface), called the Hamiltonian of the system. The plant requires, most of the time, the convergence at different fixed points and at the same time in different ways (different behaviors). This phenomenon is possible by modifying the initial energy surface. Modification of the energy surface can be achieved by external (generalized) forces. The formalism suggested in this paper allows the calculation of generalized forces and, finally, to obtain the mentioned changes.

Using Tensor-Type Formalism in Causal Networks

R. C. Pozna Á Ballagi Radu Emil Precup

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2024-01-01

Volume: 21

Issue: 10

Page Range: 75-91

Description:

The causal network is a possible description of complex phenomena, and several domains, for example, Machine Learning, Social Science, and Artificial Intelligence. Although a successful solution is referred to in this paper, the field inherently faces challenges. Among these, the work identified that the formalism used is time-consuming and difficult to understand. Consequently, the approach proposed in this paper consists in transcribing this formalism in a tensor form. This goal is accomplished in three steps: first common tensor formulas are proposed for direct and inverse models; second these formulas are adapted for the network primitives; in the end the primitive and consequently the formula composition is analysed. To facilitate the understanding of the proposed formalism, the paper describes several examples. This paper is dedicated to Prof. Imre J. Rudas, to celebrate his 75th anniversary.

On the Use of Quaternions, in the Translated Reference Frame Formalism

R. C. Pozna Radu Emil Precup

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2023-01-01

Volume: 20

Issue: 6

Page Range: 195-214

Description:

The approaches dedicated to the geometric model of the object, in the object-oriented modeling framework, specific to robots, are focused on the computation of the position of the elements, relative to a global reference frame. One important problem, in this regard, is the direct geometry, which starts with the initial data represented by the generalized coordinates and parameters of each element (in its own reference frame) and calculates the configuration of the structure in the global reference frame. This paper extends the Authors’ geometrical modeling approach, referred to as the translated reference frame formalism, by changing the mathematical apparatus of homogeneous transformations with that specific to quaternions. This new approach has three main advantages over the state-of-the art, namely, it simplifies substantially the configuration modeling, the transformation parameters are intuitive, and the computation is substituted with the operation of choosing a suitable transformation that belongs to a set of six homogeneous transformations. The suggested approach is validated by the computation of the geometric models of two illustrative robotic examples. The source codes are available in a public repository.

Hybrid Particle Filter-Particle Swarm Optimization Algorithm and Application to Fuzzy Controlled Servo Systems

R. C. Pozna E. M. Petriu Radu Emil Precup Ernö Horváth

Publication Name: IEEE Transactions on Fuzzy Systems

Publication Date: 2022-10-01

Volume: 30

Issue: 10

Page Range: 4286-4297

Description:

This article presents a hybrid metaheuristic optimization algorithm that combines particle filter (PF) and particle swarm optimization (PSO) algorithms. The new PF-PSO algorithm consists of two steps: the first generates randomly the particle population;and the second zooms the search domain. An application of this algorithm to the optimal tuning of proportional-integral-fuzzy controllers for the position control of a family of integral-type servo systems is then presented as a second contribution. The reduction in PF-PSO algorithm's cost function allows for reduced energy consumption of the fuzzy control system. A comparison with other metaheuristic algorithms on canonical test functions and experimental results are presented at the end of this article.

Model-Free Control of Finger Dynamics in Prosthetic Hand Myoelectric-based Control Systems

R. C. Pozna E. M. Petriu Radu Emil Precup Teodor Adrian TEBAN Adriana ALBU Raul Cristian ROMAN

Publication Name: Studies in Informatics and Control

Publication Date: 2020-01-01

Volume: 29

Issue: 4

Page Range: 399-410

Description:

This paper proposes an approach to the tuning of model-free controllers for the midcarpal joint angles, which are important finger angles that ensure the desired finger dynamics in prosthetic hand myoelectric-based control systems. The process in these control systems is characterized by fuzzy models that operate with myoelectric signals obtained from eight myoelectric sensors and past inputs and/or outputs, where the controlled outputs are five finger angles. Since the fuzzy models exhibit very good performance as shown in authors’ recent papers that produced evolving fuzzy models, they are used to simulate the process behaviour. The Multi Input-Multi Output (MIMO) control system structure consists of five separate Single Input-Single Output control loops with the most simple model-free controllers represented by intelligent Proportional (iP) controllers, separately designed and tuned for each finger. Digital simulation results are included to suggestively illustrate the very good performance of the control systems with iP controllers. The MIMO control system performance is compared with that of the same system but with Proportional-Integral controllers, which are optimally tuned in a model-based manner by a metaheuristic Grey Wolf Optimizer (GWO) algorithm. The fair comparison is ensured by the optimal tuning of the free parameters of iP controllers in a model-based manner using GWO.

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2018-01-01

Volume: 15

Issue: 2

Page Range: 231-249

Description:

Coverage path planning for mobile robots aims to compute the shortest path that ensures the overlap of a given area, with applications in various domains. This paper proposes a coverage path planning strategy, referred to as Iterative Structured Orientation Coverage, which has two main advantages over the state-of-the-art, namely it is it versatile and it is capable to handle complex environments. The path planning strategy is expressed as three new approaches to coverage path planning. The suggested approaches are validated by simulation and experimental results.

On a translated frame-based approach to geometric modeling of robots

R. C. Pozna Radu Emil Precup

Publication Name: Robotics and Autonomous Systems

Publication Date: 2017-05-01

Volume: 91

Issue: Unknown

Page Range: 49-58

Description:

The geometric modeling gives the structure configuration and enables the derivation of the kinematic or dynamic models of robots, it involves a procedure for reference frames definition and a specific formalism that allows the poses transformations from a reference frame to another one. This paper proposes a new geometrical modeling approach, referred to as the translated frame-based approach, which has two main advantages over the state-of-the art, namely the reference frames definition is intuitive and it eliminates the computation of the transformation operators. The frames definitions are reduced to apparent translations of the base frame and the computation is replaced with choosing an operator from a collection of six operators that cover all transformation possibilities. The suggested approach is validated by the computation of the geometric models of a PUMA robot and a redundant robot.

A novel pose estimation algorithm for robotic navigation

R. C. Pozna P. Földesi Radu Emil Precup

Publication Name: Robotics and Autonomous Systems

Publication Date: 2015-01-01

Volume: 63

Issue: P1

Page Range: 10-21

Description:

This paper proposes a new pose estimation algorithm in the framework of robotic navigation problems. The algorithm gives the mobile robot (MR) pose on the basis of the difference between the MR desired pose and the MR current pose. In this regard the MR sensor readings and the readings of a virtual sensor are employed. The algorithm is advantageous in comparison with other pose estimation algorithms including those based on classical filter approaches because of the small computation time. Simulation and real-world experimental results are included to illustrate the effectiveness of the pose estimation algorithm and its potential for integration in MR control structures and algorithms.

Publication Date: 2014-09-04

Volume: Unknown

Issue: Unknown

Page Range: 1304-1310

Description:

This paper illustrates developments of signatures for Artificial Intelligence (AI) applications. Since the signatures are data structures with efficient results in modeling of fuzzy inference systems and of uncertain expert systems, the paper starts with the analysis of the data structures used in AI applications from the knowledge representation and manipulation point of view. An overview on the signatures, on the operators on signatures and on classes of signatures is next given. Using the proto fuzzy inference system, these operators are applied in a new application of fuzzy inference system modeled by means of signatures and of classes of signatures.

Applications of signatures to expert systems modelling

R. C. Pozna Radu Emil Precup

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2014-01-01

Volume: 11

Issue: 2

Page Range: 21-39

Description:

This paper offers a new approach that applies the signatures to expert systems modelling. Signatures and their operators, viewed as a generalization of fuzzy signatures, represent a convenient framework for the symbolic representation of data. The models are derived by a three-step algorithm that maps the signatures onto expert systems. An expert systems modelling algorithm is given. Our algorithm has two inputs, the knowledge base, i.e., the rules, and the data base, i.e., the facts, and it constructs the signatures which represent models of expert systems. The algorithm is advantageous because of its systematic and general formulation allowing for the modelling of uncertain expert systems. The theoretical results are exemplified by a case study which produces models of a Bayesian expert system with mechatronics applications.

Stability analysis and design of a class of MIMO fuzzy control systems

R. C. Pozna Marius L. Tomescu E. M. Petriu Radu Emil Precup Stefan Preitl János Fodor

Publication Name: Journal of Intelligent and Fuzzy Systems

Publication Date: 2013-07-18

Volume: 25

Issue: 1

Page Range: 145-155

Description:

This paper presents a new stability analysis method dedicated to a class of fuzzy control systems (FCSs) controlling multi input-multi output (MIMO) nonlinear processes by means of Takagi-Sugeno-Kang fuzzy logic controllers (FLCs). The stability analysis of the FCSs is carried out using LaSalle's global invariant set theorem by the separate stability analysis of each fuzzy rule in MIMO fuzzy control systems. Therefore the complexity of the stability analysis is reduced and the adding of new fuzzy rules can be conducted easily; this modification of FLC structure requires the fulfillment of only one of the conditions of the stability analysis theorem suggested in this paper. Another advantage of the stability analysis approach proposed in this paper is that the derivative of the Lyapunov function candidate must be only negative semi-definite in comparison with Lyapunov's stability theorem where it must be negative definite. The conservativeness of stability conditions is thus reduced, and this enables the convenient design of FLCs. The applicability and efficiency of the theoretical results are illustrated by numerical simulations for a representative MIMO process which deals with the level control in a three spherical tank system. © 2013-IOS Press and the authors.

Iterative Feedback Tuning of Anti-Windup PI Fuzzy Control of Tower Crane System Payload Position

R. C. Pozna Radu Emil Precup Miruna Maria Damian Raul Cristian ROMAN

Publication Name: IEEE International Conference on Fuzzy Systems

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

This paper proposes the data-driven tuning of low-cost Proportional-Integral (PI) fuzzy control of the payload position of tower crane systems using Iterative Feedback Tuning (IFT). A back-calculation and tracking anti-windup diagram is included to prohibit integrator windup and compensate for the process's dead-zone and saturation nonlinearity. A two-stage tuning strategy is proposed. In the first stage, the parameters of the fuzzy logic part of the PI fuzzy controller and the anti-windup tracking gain are optimally tuned in a model-based manner using an original version of the hybrid Particle Filter-Particle Swarm Optimization algorithm, improved by adding an information feedback model. In the second stage, the parameters of the linear part of the PI fuzzy controller are tuned in a data-driven manner using IFT, and then mapped to the remaining PI fuzzy controller parameters using the modal equivalence principle. The efficacy of the new data-driven fuzzy control strategy is demonstrated through experimental results, and the comparison shows the performance improvement over other strategies designed using competing optimization algorithms.
