变结构控制在液压振动台上的应用研究

Application of Variable Structure Control in Hydraulic Shaker

针对液压振动台的稳定性问题,建立了液压振动台模型,采用变结构控制设计,降低了系统维数,使得系统稳定运行在滑动平面。仿真结果表明,采用变结构控制后的液压振动台具有良好的稳定性和抗干扰性能。

To improve the stability of the hydraulic shaker, the system model was buih. Through variabel structure control method, the dimension of the system was reduced, so the system runs steadily in the slide surace. Simulation result shows that the sytem has good stability and anti-jamming performance.
