Abstract

Owing to its reliability, high precision, and performance, the permanent magnet synchronous motor (PMSM) is becoming an interesting candidate for electric vehicle traction systems. In this latter, the goal is to attain high power conversion efficiency and high mechanical speeds with great precision. Therefore, motor control is extremely crucial in EVs as a vehicle on the road is susceptible to various disturbances and load variations. In this context, a robust speed controller is required to achieve high operation performance, accurate speed tracking, minor overshoot, and disturbance rejection. In this study, a nonsingular terminal sliding mode controller (NTSMC) is suggested for the speed control of a PMSM that is powered by a three-phase voltage source inverter (VSI). NTSMC is a well-known approach that offers high-performance control and can effectively deal with parameter uncertainties and disturbances, which makes it highly recommended for PMSM speed control. The stability of the NTSMC is proven using the Lyapunov stability theory. In the end, various simulations are conducted. The proposed approach shows through simulations that it outperforms the conventional proportional integral (PI) controller. Besides, it offers accurate speed tracking, high performance control, and reduced overshoot, which demonstrates its feasibility and effectiveness.
