Development of control algorithms for electrical machines may be a difficult procedure if functional safety, software quality, reusability and expandability come into scope. These properties might be required in both of research and industrial development projects. State of the art methods and tools like model-based design (MBD) and automated code generation may help to meet these requirements. In this paper, MBD methods and a modular, reusable model architecture are presented for implementation of field oriented control (FOC)-based controller software for induction motors.
