Abstract :
Induction motors are popular among all types of electrical machines. Speed control of such motors is challenging due to coupling effect of speed-flux loops. Control is also exigent due to parametric variations, large operating range and external disturbances. A well established sliding mode control (SMC) technique is potential candidate to solve above said problems. Performance of SMC for Induction motor (IM) speed control is investigated for set point tracking, load disturbance and parametric variation. The simulation results show SMC based IM control is superior to conventional Proportional-Integral(PI) approach. The performance of SMC is further enhanced by adding PI control with SMC. It helps to remove offset present with only SMC.
