疲劳试验机电液伺服系统滑模鲁棒控制的实验研究

Experimental study on Sliding Mode Robust Control for Electro- hydraulic Servo System of Fatigue Testing Machine

本文以结构疲劳试验机电液位置伺服系统为被控对象，研究了当系统参数变化时，如何设计一种鲁棒 控制器来保证系统的稳定性和良好的跟踪性能，基于变结构控制的基本理论，提出了一种滑模控制器设计方法，并 通过实验证明了该方法的有效性。

The controlled plant is the electrohydraulic servo system of fatigue testing machine in this paper. The problem on how designing a robust controller when the parameters varying is studied. Based on the theories of the variable structure control, the designing method of a sliding mode controller is presented. The valid of the medthod is shown by real-time control robust con- trolle.
