Auto-disturbance-rejection controller used in permanent-magnet linear motor control system
自抗扰控制在永磁直线电机控制中的应用

This paper analyzes the features and problem of PID controller,and presents the principle,structure and design of the auto-disturbance-rejection controller(ADRC).Regarding motor coupling in a permanent-magnet linear motor as the internal disturbance,and taking account of the friction disturbance,we presented the simulation results when using ADRC technique.(At the) same time,the simulation results of using PID controller are also presented for the simplified motor.From the results,it (is concluded) that the auto-disturbance-rejection controller has advantage over PID controller in the disturbance rejection and (robustness.)
