摘要
为了削弱传统滑模控制在十字梁实验系统中应用所产生的抖振问题 ,运用了高阶滑模的设计思想设计了多输入多输出十字梁试验系统的输出跟踪二阶滑模控制器 ,从而实现了高阶滑模在多输入多输出系统中的应用 ,并对该系统进行了仿真 ,仿真结果表明 。
To reduce the chattering produced by traditional sliding mode controller on the cross beam experimental system, a second-order sliding mode controller was designed, based on the idea of high-order sliding mode control for output tracking the cross beam system which is a higher order and MIMO (multiinput-multioutput) nonlinear system. This method can be used high-order sliding mode control on MIMO system. The simulation shows that second-order sliding mode control can reduce chattering.
