高性能位置伺服控制系统的Simulink仿真研究

Simulink Simulation Research on High-performance Position Servo Control System

摘要:

高性能位置伺服控制系统具有响应迅速、超调量小、精度高、跟踪性能好等优点。 在传统的三闭环伺服控制系统中存在跟踪滞后、轻载超调量大等问题。 为此,我们在伺服控制系统的电流环和速度环中引入前馈控制环节解决滞后性的问题,在系统位置环中设置微分负反馈环节来减小超调量。 仿真实验验证了该系统已满足高性能伺服控制系统的性能要求,具有一定的工程应用价值。

Abstract:

High performance position servo control system has the advantages of rapid response, small overshoot, high pre- cision, good tracking performance, etc. In the traditional three closed-loop servo control system, there are problems of tracking lag, large overshoot of light load, etc. In order to solve the problem of hysteresis, feedforward control is introduced into current loop and speed loop of servo control system, and differential negative feedback is set in position loop to reduce overshoot. The simulation re- sults show that the system meets performance requirements of high-performance servo control system and has certain practical value.
