| Abstract | ||||
| This paper presents a comparison of two different control strategies for Squirrel-Cage Induction Motor (IM): conventional Proportional-Integral (PI) controller and modern Sliding Mode Controller (SMC). Two control laws are proposed to control speed and rotor flux independently. Convergence analysis of the SMC, based on Lyapunov theory, proved. Both strategies are investigated and simulated using MATLAB/Simulink under nominal case. Moreover, the robustness of both methods with respect to the parameters uncertainties is verified by significant simulation results. The study shows that nonlinear control strategy based Sliding mode technique possesses not only high-performance dynamic characteristics, but also robustness with respect to parameter variations and external load disturbances compared to PI controller. | ||||
