The increase in operating as well as environmental temperature of an electric vehicle (EV) motor drive causes significant variations in its performance parameters such as rotor, stator resistance and mutual inductance. This variation results in the overall performance degradation of electrified powertrain in the form of excessive fuel (battery) consumption and inability to meet the desired terminal characteristics such as speed, torque and flux. To mitigate this issue, a robust linear parameter varying (LPV) control incorporated with linear matrix inequalities (LMIs) is presented in this work that ensures L2 gain bound and closed-loop control system stability. A comparison of sliding mode control (SMC) is made with the proposed controller to validate its robustness. In order to verify the efficacy of LPV controller, its performance is tested against a New European Driving Cycle (NEDC) in MATLAB Simulink environment. The nonlinear simulation results gurantee the excellence of LPV performance.
