Compensating the Performance and Loss of Life of an Induction Machine based Electrified Powertrain using Robust LPV Controller

This work deals the influence of rise in ambient and operating temperatures on road load demands and loss of lifetime (aging) for an induction machine based electrified powertrain. The performance of conventional field-oriented control is deteriorated in harsh operating conditions. In this work, a robust Linear Parameters Varying (LPV) based field-oriented control is proposed to meet the road loads demands and minimizing the loss of lifetime (aging) of an electric machine. The performance of the proposed control technique is verified and investigated for the electrified powertrain of a three-wheeled vehicle used in urban transportation of Asian countries. The Federal Urban Driving Schedule is adopted for the simulation validation of the proposed approach. The nonlinear simulation results show that torque demands and lifetime of an induction machine based electrified powertrain can be improved with little compromise in the performance.
