Abstract
Electric and hybrid vehicle drive systems are commonly equipped with Permanent Magnet Synchronous Motors, because they offer high efficiency in broad range of speed and torque, and also due to special current development techniques they can work with high speeds. The paper presents simulation results for predictive current controller used in PMSM drive system. The results were obtained for high speed operations with Maximum Torque Per Ampere (MTPA) control strategy, which allows to develop set torque value with the smallest possible currents values. Predictive current controller equations are based on IPMSM mathematical model which considers Ld and Lq inductances changes. Additionally MTPA strategy also considers inductances changes in d- and q-axis.
