摘　　要：为了准确、快速地实现对永磁同步电动机速度的控制,设计了一种新型的速度控制方法。首先,针对传统自扰动非线性函数的缺陷,设计了一种新型的非线性函数,并在此基础上开发了一种新型的扩张状态观测器;然后利用分数阶跟踪微分器代替传统跟踪微分器,完成了基于改进型自抗扰电机调速控制系统的设计;最后,利用MATLAB搭建控制器控制永磁同步电动机速度的仿真模型,并进行了仿真试验分析。结果表明,改进型自抗扰控制器具有更好的跟踪和响应能力。In order to accurately and fast control the speed of permanent magnet synchronous motors,a new speed control method is designed.Firstly,a new type of nonlinear function is designed to address the shortcomings of traditional self disturbance nonlinear functions,and a novel extended state observer is developed based on it.Then a fractional order tracking differentiator is used to replace the traditional tracking differentiator to complete the design of an improved self disturbance rejection motor speed control system.Finally,a simulation model of the controller controlling the speed of permanent magnet synchronous electric motors is built using Matlab,and simulation experiments are conducted for analysis.The results indicate that the improved self disturbance rejection controller has better tracking and response capabilities.
