摘要
该系统以MC9S12DG128为控制核心,软件实现角度细分,采用固定电压斩波PWM占空比和角度控制结合的控制方法,分析电流特性,实现对电机的控制。最后给出了系统的试验结果和波形,表明该系统具有良好的运行性能。
The system is based on MC9S12DG128 and realized angular fine division by software. Angular position Control combined with fixed Pulse-Width Modulation and voltage- chopping control is used in the system.Realize the control of motor by analysising the phase current characteristics. Finally, the results and waves of experiment are given,which indicates that the control system has favorable operating performance.
