摘要
针对永磁无刷直流电机运行过程中存在的转矩波动干扰问题,提出了一种基于PLC的电机转矩波动抑制的自抗扰控制方法,将被控对象简化为两个非线性串联环节,分别设计了各自的自抗扰控制器来实现永磁无刷直流电机的内环转矩控制与外环转速控制。
According to the interference problems of torque ripple of permanent magnet brushless DC motor in operation process, a method of self-anti-disturbance control of torque ripple suppression based on PLC is proposed. Two kinds of self-an- ti-disturbance controllers are designed in order to implement inner ring and outer ring torque control of permanent magnet brushless DC motor.
