Research of Tank Servo Control System Based on Dual-mode and Dual-loop ADRC of PMSM

In order to realize the high-precision control of tank servo system under the road disturbance during driving, an active disturbance rejection controller (ADRC) based on dual-mode and dual-loop structure is designed and introduced into the control of permanent magnet synchronous motor. Firstly, this paper introduces the mathematical model of permanent magnet synchronous motor, then uses Matlab / Simulink software to design its three closed-loop control structure, which is a basic control structure, and then designs a dual-mode and dual-loop ADRC under the same motor parameters. The simulation results show that the control performance of the ADRC based on dual-mode and dual loop structure is better, and the motor servo control system has faster response speed, smaller tracking error.
