A robust decoupling current multivariable controller for a permanent synchronous machine is designed using a linear parameter variant (LPV) of Hinfin control. This controller is scheduled with the rotor speed. Closed loop sensitivity functions analysis and simulation results evaluate the performance and the stability robustness of the resulting controller over all admissible PMSM operating range and under both unstructured disturbances related to the implementation and uncertainties in stator parameters
