摘要:

针对永磁同步电机(permanent magnet synchronous motor,PMSM)无传感器控制中转子速度和位置的估计精度不高、系统抖振等问题,提出一种基于自适应模糊神经网络(adaptive neuro-fuzzy inference system,ANFIS)优化的磁链滑模观测器(flux sliding mode observer,FSMO)采用经过ANFIS优化的FSMO实现对观测器增益的在线调节,减少系统抖振;采用改进的锁相环(phase locked loop,PLL),提高对转子速度及位置的估计精度。实验结果表明:ANFIS优化的FSMO能够有效地提高PMSM无传感器控制中转子速度和位置的估计精度,减少系统抖振。

Abstract:

Aiming at the low estimation accuracy of rotor speed and position and the system chattering in sensorless control of permanent magnet synchronous motor (PMSM), an adaptive neuro-fuzzy inference system (ANFIS) is proposed to optimize the flux sliding mode observer(FSMO). Compared with the traditional sliding mode observer, the FSMO improves the estimation accuracy of the rotor flux. The FSMO optimized by ANFIS realizes the on-line adjustment of the observer gain and reduces the system chattering. The improved PLL improves the estimation accuracy of the rotor speed and position. A simulation platform is established to verify the results which show that the ANFIS optimized FSMO can effectively improve the accuracy of the rotor speed and position estimation in PMSM sensorless control and reduce the system chattering.

Key words: flux sliding mode, adaptive neuro fuzzy inference system, phase locked loop, sensorless control, permanent magnet synchronous motor
