Research on Control Method of Permanent Magnet Synchronous Motor Speed Control System Based on Improved ADRC
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 short-comings 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 differ-entiator to complete the design of an improved self disturbance rejection motor speed control system.Final-ly,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.
