Comparative Performance Assessment of Predictive Torque Control Strategy for Motor Drive Applications

Recently the majority of research in the field of predictive torque control (PTC) focuses on torque ripple and computational burden reduction. The main disadvantage of the traditional PTC strategy is the high computational time requirement, and it restricts the utilization of the PTC in automotive application. In this paper, a new PTC is used based on the modification of conventional PTC that reduces the computational time. At the same time, the modified PTC proposed in this paper reduces semiconductor losses and thermal stress. Moreover, a comparative analysis between conventional PTC and modified PTC has been conducted in terms of driving, electrical and thermal performance. It is found from a simulation study in MATLAB/Simulink® that the modified PTC reduces the switching loss by up to 20%, while the efficiency is increased by more than 5% compared to a conventional PTC. Finally, a reduction in the heatsink temperature response is also noticed during this assessment.
