摘要
分析了BLDCM的数学模型,运用MATLAB仿真软件搭建了无刷直流电机控制系统的仿真模型。本系统采用了速度PID控制、电流迟滞控制的双闭环控制方案,电流迟滞控制是为了更方便地跟踪PWM信号并控制逆变器开关的导通与关断。通过试验结果可以看出系统能够稳定运行,进而验证了该方案的可行性。
The mathematical model of a BLDCM was analysed ,and the simulation model of BLDCM control system was set up using MATLAB simulation software .This system adopted the scheme of double closed loop control including PID speed control and the current hysteresis control ,in order to track PWM signal and control the inverter switch on and off more conveniently .The test result shows that system works well ,and the feasibility of the scheme is verified .
