This paper presents a new method for determining the steady-state machine parameter sensitivities of induction machine speed sensorless control algorithms, which are utilizing unscented Kalman filter (UKF) and direct rotor field oriented control (DRFOC). Sensitivity influence of the UKF is investigated by alternative noise parameters and pointed out that selection of noise parameters may influence the flux and torque sensitivities of the entire system with respect to stator resistance variations. In order to obtain a better picture, the sensitivities are calculated for various operating points resulting in sensitivity maps. For this, a computationally efficient calculation method is applied by using the steady-state system equations.
