Modified Multi-Vector Predictive Current Control for High-Performance EV Induction Motor Drives

Predictive Current Control (PCC) is an effective technique for managing constrained nonlinear systems requiring high dynamic performance, especially in industrial and transportation applications. This paper presents a robust multi-vector PCC scheme for Electric Vehicle (EV) Induction Motor (IM) drives, designed to maintain a fixed switching frequency with improved performance. The scheme combines symmetric three-vector PCC with slip-speed based dwelling time to introduce a simplified voltage vector (VV) preselection method, covering all operating modes and ensuring accurate reference voltage tracking, enhanced sector identification, and reduced computational complexity. Additionally, a Maximum Torque Per Ampere (MTPA) strategy is integrated to extend the speed range, ensuring efficient performance both below and above the rated speed while maintaining voltage constraints. Experimental results demonstrate the proposed scheme’s superior dynamic response, computational efficiency, and wide-speed adaptability for EV using EUDC driving scheme.
