摘　　要：针对常规PI在无刷电机调速中控制精度低及动态性能差,无法满足裁断机对动力辊电机速度控制要求,本文提出了一种自适应模糊PI控制方法。该方法应用于无刷直流电机双闭环控制的速度外环控制,提高了无刷直流电机的控制精度和动态响应性能。通过Matlab进行仿真,仿真结果表明,采用自适应模糊PI控制相对常规PI控制,无刷直流电机的调速系统具有很好的动态和静态性能,快速响应,超调量小,抗干扰能力强,鲁棒性好。In the conventional PI control of brushless motor speed low precision and dynamic performance is poor, unable to meet the power roller cutting machine for motor speed control requirements, we propose an adaptive fuzzy PI control method. The method is applied to double-loop control of brushless DC motor speed outer control, improved control accuracy and dynamic response performance brushless DC motor. Through Matlab simulation results show that the adaptive fuzzy PI speed control system to control relative to conventional PI control, brushless DC motor has a good dynamic and static performance, fast response, small overshoot, and strong anti-jamming capability, robustness.
