基于线性自抗扰控制技术的永磁同步电机控制策略研究

永磁同步电机(PMSM)具有体积小、高速度、高精度等优势,广泛应用于现代工程实际当中。在多数情况下其控制策略采用经典的PID控制,但较多的实际复杂环境当中,传统的PID所暴露的固有缺陷已经无法满足PMSM的控制高效性。采用先进的线性自抗扰控制策略,其具有不依赖具体对象模型,控制器自身可以估计补偿作用于被控对象的所有扰动的优势,实验仿真结果表明,该方案有效抑制了扰动,进而提高了系统的控制性能。

Research on Linear Active Disturbance Rejection Control Technology of Permanent Magnet Synchronous Motor

Permanent Magnet Synchronous Motor(PMSM)has the advantages of small size,high speed and high precision,and is widely used in modern engineering practice.In most cases,its control strategy uses classic PID control.However,in many practical and complex environments,the inherent defects exposed by traditional PIDs can no longer meet the control efficiency of PMSM.This paper adopts advanced linear ADRC control strategy.With the advantage of not relying on specific object models and the controller itself,it can estimate and compensate all disturbances acting on the controlled object.
