Design of Pure Electric Vehicles’ Drive Motor Controller Based on dsPIC

Abstract:

To meet the industry demands of the drive motor controller of the pure electric vehicles, this paper introduces a design of the high-power brushless DC motor controller at the core of dsPIC30F6010A. Through the establishment of permanent magnet brushless DC motor (PMBLDC) mathematical model and the analysis of the running principle of it, the control scheme of pure electric vehicles was presented and the drive circuits, protection circuits and software programming of PMBLDC controller were designed in this paper. The paralled IGBT module is adopted as the drive circuits to solve the heat dissipation issues under the high current, PID is chosen as the control algorithm and cascade control is designed as the speed regulation.The simulation by MATLAB/simulink shows that the control scheme is reasonable, the system has fast response and smooth running.
