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.
