The variation in rotor resistance caused by the bchange in operating and ambient temperature deteriorates the dynamic response of induction motors. This paper presents an output feedback Linear Parameter Varying (LPV) control technique using input-output feedback linearization and H ∞ control theory to mitigate this problem. The d-q stator currents in the stationary frame can be expressed as an LPV system due to their affine dependence on rotor resistance that is taken as the time varying parameter. The LPV controller synthesis is based upon the Linear Matrix Inequality (LMI) approach. The closed loop system comprises of two ...

The LPV controller synthesis is based upon the Linear Matrix Inequality (LMI) approach. The closed loop system comprises of two nested loops: an inner loop of d-q stator currents and an outer loop of rotor angular velocity. The nonlinear simulation results have been incorporated to ensure robustness of the designed control system. From these results, it is found that the proposed controller provides an excellent tracking performance over the entire operating range of rotor resistance.
