INTEGRATED PARAMETER CONTROL SYSTEM FOR DRIVING MOTOR MOBILE INTERNET

Abstract

The brushless dc motor is a new kind of stepless variable speed motor, convenient maintenance, high efficiency and high performance is excellent, has on many occasions to replace other kinds of motors. Therefore, the further research of brushless dc motor has become a hot spot, has broad market prospects. In brushless dc motor as the research object, this paper designed a set of brushless dc motor based on TMS320F2812 DSP closed-loop variable frequency speed regulation system. On brushless dc motor speed control system of the basic composition, working principle, mathematical model and control strategy is commonly used, and on this basis of brushless dc motor double closed-loop control experiments, the results show that under the double closed loop control, brushless motor can run stable and reliable.
