On Control Strategy of Permanent Magnet Synchronous Motor for Micro-electric Vehicle

For the performance requirements of micro-electric vehicle, permanent magnet synchronous motor (PMSM) with its excellent performance has been widely used in the field. Based on the mathematical models of PMSM in different coordinate systems, the control strategies of PMSM are analyzed in detail and improved by using intelligent control technology. Combined with the engineering project of the enterprise, simulation experiments are carried out in different working conditions. Based on the actual parameters of micro-electric vehicle and PMSM, the double closed-loop vector control system is taken as an instance object and established in MATLAB/Simulink environment. At the same time, the fuzzy controller with parameter self-adjusting capability is introduced to improve the traditional PI regulator of the speed loop, and achieves better control effect. In the design of driving system for micro-electric vehicle, the control strategy has a certain practical significance.
