一种机电位置伺服系统的抑扰控制策略及其实现
A Disturbance Suppression Control Strategy and Its Realization for an Electromechanical Position Servo System
摘要
Abstract
The disturbance-suppression methods are discussed for solving the severe disturbance from the automatic three-coordinate positioning and installation system of a certain type of motor test equipment. Firstly, a kinetic model of the Z-axis lifting system with complicated internal disturbance factors and significant external load is established, and then an AC driven full closed-loop electromechanical position servo system is established to prevent the initial impact of various closed-loop internal disturbances. In order to further improve the system's anti-disturbance abilities, the advanced active-disturbances rejection controller (ADRC) is introduced in the positional loop controller of the fully closed-loop control system. A MATLAB/Simulink simulation test was carried out based on this full closed-loop position servo system and a contrast analysis was made between the disturbance resistance effects of ADRC control and PID control for the position loop. The results show that for the position tracking performance under the external disturbance of a constant load and the position holding performance under the internal disturbance of electrical impedance, the ADRC control is better than the PID control. Finally, the corresponding tests were completed using the test equipment, and the simulation results were further verified.关键词
