A LPV (Linear Parameter Varying) control strategy is implemented in order to reduce torque ripple in HEV (Hybrid Electric Vehicles). The ICE (Internal Combustion Engine) ripples are attenuated by a PMSM (Permanent Magnet Synchronous Machine). Because the ICE motor generates persistent disturbances which vary with the rotational speed, it is necessary to design a LPV controller. The control strategy uses the internal model principle. The controller is designed by several steps which includes linear matrix inequalities optimization. A test bed simulator is used through a complete modeling of a hybrid powertrain propulsion. Simulation results show the effectiveness of the control.
