摘　　要：为了实现无刷直流电机的控制数字化和精确可控性,以及解决普通PID算法在无刷直流电机应用中出现的问题,分析了一种以单片机为核心的硬件控制系统方案。该控制系统由无刷直流电机I、R2130,IRF540等构成,以AT89C51为核心,控制算法采用变速积分PID算法。仿真结果证明成功解决了普通PID算法中的积分饱和现象,系统响应速度快,稳定性好,提高了无刷直流电机的可控性。It analyzes scheme of control system organization based on SCM,to realize digital of measurement and precious controlling in brushless DC motor,and to resolve the questions which appear in B1.DC PID regulator . The control system is consists of IRF540, IR2130, a BI.DC and so on. In this system AT89C51 is adopted as the core controller. The digital PID control algorithm with the variable-integrator is used in this system,the simulation and experiment results show that the algorithm can successfully be used to free from the integral saturation of common PID, and the system has such features as real time, stability,measurement performance and etc.
