摘要: 为了优化永磁同步电机无速度传感器的控制策略,对模型参考自适应永磁同步电机控制算法进行了改进。设计了基于同步旋转坐标系下的定子磁链状态方程模型参考自适应的修正补偿,改善了可调模型的可控性,转速抖动小,收敛速度快;理论验证和仿真结果表明,改进后的控制策略对电机实际参数的依赖性低,适用于参数可发生变化的实际工况,提高了永磁同步电机矢量控制的鲁棒性以及系统稳定性。

Abstract: In order to optimize the control strategy of permanent magnet synchronous motor(PMSM) and improve the speed sensorless algorithm for PMSM based on model reference adaptive system(MRAS), a feedback section for integral compensation based on MRAS stator flux state equation under synchronous frame was designed to increase the controllability of the controlled model, reduce the vibration and settling time of the rotation speed. Theoretical analysis and simulation results show that implementing the improved control technique could bring low dependence on the actual motor parameters and is applicable to parameters fluctuated working conditions, which enhances the robustness and system stability of PMSM field-oriented control.

Key words: permanent magnet synchronous motor(PMSM), speed sensorless, adaptive control, model reference adaptive system(MRAS), field-oriented control
