Loop-shaping H∞ control for a doubly fed induction motor

This paper deals with a doubly fed induction machine (DFIM) where both sides are supplied by two PWM inverters. The study consists in elaborating a robust vector control of the machine by the loop- shaping H_infin approach. The H_infin loop-shaping theory is presented in brief; then it is applied to the control of the DFIM. The simulation results prove that the implementation of the H_infin controllers for currents, fluxes and speed loops leads to excellent robustness in stability and good dynamic performance even with large electrical and mechanical parameters uncertainty.
