摘要：
During missile launch and flight, the electric servo system is subjected to loads such as engine ignition, aerodynamic loods, and rudder impact. Increase of structural wear leads to the structural gaps in the system. It greatly reduces the transmission stiffness and aggravates the harm caused by resonance. This paper proposes an improved active disturbance rejection controller (ADRC) to improve the tracking performance of the electric servo system. First, the mechanism of mechanical resonance for the electric servo system is analyzed. Then, the linear ADRC is described and the method to select parameters is given by improved particle swarm optimization (P S O) algorithm. Furthermore, the feasibility of this controller is demonstrated through a simulation analysis. Finally, the experimental results of electric servo system indicate that the improved ADRC can improve stability and dynamic performance. © 2024 Chinese Institute of Electronics. All rights reserved.
