Abstract

Purpose

This paper mainly aims to deal with the problems of uncertainties including modelling errors, unknown dynamics and disturbances caused by load mutation in control of permanent magnet synchronous motor (PMSM).

Design/methodology/approach

This paper proposes an enhanced speed sensorless vector control method based on an active disturbance rejection controller (ADRC) for a PMSM. First, a state space model of the PMSM is obtained for the field orientation control strategy. Second, a sliding mode observer (SMO) based on back electromotive force (EMF) is introduced to replace the encode to estimate the rotor flux position angle and speed. Third, an infinite impulse response (IIR) filter is introduced to eliminate high frequency noise mixed in the output of the sliding mode observer. In addition, a speed control method based on an extended state observer (ESO) is proposed to estimate and compensate for the total disturbances. Finally, an experimental set-up is built to verify the effectiveness and superiority of the proposed ADRC-based control method.

Findings

The comparative experimental results show that the proposed speed sensorless control method with the IIR filter can achieve excellent robustness and speed tracking performance for PMSM system.

Research limitations/implications

An enhanced sensorless control method based on active disturbance rejection controller is designed to realize high precision control of the PMSM; the IIR filter is used to attenuate the chattering problem of traditional SMO; this method simplifies the system and saves the total cost due to the speed sensorless technology.

Practical implications

The use of sensorless can reduce costs and be more beneficial to actual industrial application.

Originality/value

The proposed enhanced speed sensorless vector control method based on an ADRC with the IIR filter enriches the control method of PMSM. It can ameliorate system robustness and achieve excellent speed tracking performance.

基于自抗扰控制器的永磁同步电机系统增强无传感器控制:设计与硬件实现
目的研究永磁同步电动机控制中存在的建模误差、动力学未知和负载突变引起的扰动等不确定性问题。本文提出了一种基于自抗扰控制器(ADRC)的永磁同步电机无速度传感器矢量控制方法。首先,建立了永磁同步电机磁场定向控制策略的状态空间模型。其次,引入基于反电动势(EMF)的滑模观测器(SMO)代替编码来估计转子磁链位置、角度和速度;第三,引入无限脉冲响应滤波器消除滑模观测器输出中的高频噪声。此外,提出了一种基于扩展状态观测器(ESO)的速度控制方法来估计和补偿总扰动。最后,通过实验验证了该控制方法的有效性和优越性。对比实验结果表明,采用IIR滤波器的无速度传感器控制方法对永磁同步电机系统具有良好的鲁棒性和速度跟踪性能。为实现永磁同步电机的高精度控制,设计了一种基于自抗扰控制器的增强型无传感器控制方法;采用IIR滤波器对传统SMO的抖振问题进行了衰减;由于采用了无速度传感器技术,该方法简化了系统,节省了总成本。实际意义使用无传感器可以降低成本,更有利于实际工业应用。提出了一种基于自抗扰和IIR滤波器的增强型无速度传感器矢量控制方法,丰富了永磁同步电机的控制方法。该方法可以提高系统的鲁棒性,实现良好的速度跟踪性能。
