Abstract :
A chattering alleviation control algorithm was applied to a vector-controlled induction motor servo system to practically eliminate the chattering problem. The strategy consists of hybridizing the conventional sliding mode control with linear state feedback. The servo system with the proposed control strategy was analyzed. studied by simulation, and verified experimentally in the laboratory. The performance of the drive is shown to be practically free from chattering problems. The system simulation study was extended to conventional sliding mode control and sliding mode control with a low-pass filter, and the comparison of the results indicates the superiority of the new control algorithm
