永磁同步电动机的一种新型转矩鲁棒控制方法

A Novel Robust Torque Control Method for Permanent Magnet Synchronous Motor

基于Lyaponov稳定性理论,针对永磁同步电动机(PMSM)提出了一种结构简单的转矩控制方法。由于这种控制方法是基于Lyaponov理论提出的,所以保证了整个控制系统的稳定性。使用带有跟踪误差积分项的Lyaponov函数,提高了跟踪误差的收敛速度,实现了电磁转矩对给定值的全局一致跟踪。仿真结果表明了这种控制方法的有效性。

This paper presents a kind of novel and simple torque controller for Permanent Magnet Synchronous Motors （PMSM） based on Lyaponov stability theorem. The overall stability of the system is guaranteed using Lyaponov function. The penalizing integral terms of the tracking errors are used in the Lyaponov function to enhance the convergence speed. The tracking error is shown to be globally uniformly converged. Simulation results are presented to show the effectiveness of the approach,
