Abstract :
This paper presents the design of the controller for the stator current of an induction motor. In the design of the controller the use of synchronous and stationary reference frames is considered. It is also investigated how the controller design is influenced by the selection of the sampling period. Besides that, it is discussed how to exploit the capability of modern power converters to operate at high switching frequencies to improve the performance of the drive system. Simulation and experimental results are presented
