摘要
研究了基于DSP和MC33035组成的高速高效无刷直流电机的数字控制系统。DSP实现控制算法,MC33035完成有位置传感器无刷直流电机的换相控制和功率器件的驱动。该系统能实现对高速惯性动量轮电机(最高转速30 000 r/min)的驱动。采用软件锁相环算法后,转速控制精度可达0.02%,并具有较高的效率和可靠性。
A digital control system based on DSP and MC33035 for high speed & efficiency Brushless DC Motor(BDCM) is presented, in which the speed control algorithm is realized by DSP, while the commutation of BDCM with sensors and the drive of the power module are realized by MC33035. The system can be applied to the inertia momentum wheel. The controlled speed precision can reach 0.02% by means of software phase-locked loop. High efficiency and reliability are proved by experiments.
