چکیده:

In this article we investigate on robust mixed-sensitivity H∞ control for speed and torque control of induction motor (IM). In order to simplify the design procedure the Takagi—Sugeno (T—S) fuzzy approach is introduced to solve the nonlinear model Problem. Loop-shaping methodology and Mixed-sensitivity problem are developed to formulatefrequency-domain specifications. Then a regional poleplacement output feedback H∞ controller by using linear matrixinequalities(LMIs) teqnique for each linear subsystem of IM T-S fuzzy model is employed. Parallel Distributed Compensation(PDC) is used to design the controller for the overall system . Simulation results are presented to validate the effectiveness of the proposed controller even in the presence of motor parameter variations and unknown load disturbance
