摘要
本文针对永磁同步电机无位置控制进行研究,为了避免传统控制方法所采用的低通滤波器带来的相位偏移,进而造成转速控制误差的问题,结合模糊滑模观测器提出一种新的控制方案。控制方案的设计基本流程为:永磁同步电机建模、基于模糊滑模观测器的无位置传感器控制、控制策略切换。通过应用新的控制方法验证,该方法可有效减小转速控制误差,提高控制精度。
This article studies the position free control of permanent magnet synchronous motors.In order to avoid the phase shift caused by the low-pass filter used in traditional control methods,which can cause speed control errors,a new control scheme is proposed by combining fuzzy sliding mode observer.The basic design process of the control scheme includes:modeling of permanent magnet synchronous motor,sensorless control based on fuzzy sliding mode observer,and control strategy switching.By applying a new control method,it has been verified that this method can effectively reduce speed control errors and improve control accuracy.
