Persistent disturbances rejection on Internal Combustion engine torque in Hybrid Electric Vehicles

In this paper, a new control strategy of torque ripple reduction in Hybrid Electric Vehicles (HEV) is presented. The Internal Combustion Engine (ICE) ripples are reduced by a Permanent Magnet Synchronous Machine (PMSM). The control strategy uses the internal model principle. It is based on dynamic output feedback controller synthesis. The controller design problem is reduced to solving a system of linear matrix inequalities (LMIs). It is formulated in the time domain with regard to the main order of the fluctuations. A test bed simulator is developed through a complete modeling of a hybrid powertrain propulsion. Simulation results show the control approach interest.
