Abstract :
This paper deals with real-time control of an induction motor based on a digital signal processor (DSP) TMS320C31/40-MHz-based system. A sliding mode controller (SMC) is presented and compared with the well-known field orientation and input-output linearization techniques. To estimate the rotor flux, a sliding mode observer is used. Experimental results are given to highlight the performances and disadvantages of these methods with respect to rotor resistance variations
