Abstract :
In this paper, discrete-time sliding mode control is proposed for implementing an induction motor drive without varying the system structure. Very simple constant gain reaching control and sliding control are obtained to eliminate the chattering phenomenon and steady state error as well as to achieve robustness and minimized computation. For integration of the whole system, a simple field acceleration control algorithm is also derived to coordinate with the sliding mode control such that a simple 8 bit microcomputer can be used to implement a high performance induction motor drive
