| 摘 要： | 针对无刷直流电机(BLDCM)在中低速运行过程中,电机转速存在波动且动态调速特性较差的问题,提出了一种将改进型模糊自整定PI控制与PLC相结合的BLDCM调速方案。改进型模糊自整定PI控制在传统PI控制的基础上引入积分重置环节,既能够对参数进行实时调节,又避免了控制过程中积分饱和的问题。用Visual C++编写控制程序对PLC进行模块化编程。通过试验,证明了改进型方法在电机中低速运行过程中,具有响应速度快、稳定性好、无超调量等优点。

| Abstract: | In order to solve the problem of speed fluctuation and poor dynamic speed regulation characteristic of brushless DC motor (BLDCM) in the low or medium speed status, a control strategy combining advanced fuzzy self tuning PI control and PLC is proposed for BLDCM speed regulation. On the basis of traditional PI controller, the advanced fuzzy PI control strategy integrates the integral reset link with PI controller, which can not only adjust the parameters in real time, but also avoid the problem of integral saturation in the control process. The PLC is programmed by Visual C++. Experiment results prove that, the proposed control strategy has the advantages of fast response, good stability and non overshoot when the motor is running in the low or medium speed range. |
