针对未建模的动态非线性系统，根据滑动模态控制原理，导出了基于Ｌｙａｐｕｎｏｖ稳定性的一种模糊控制器设计方法；避免了以往非线性滑模控制中控制信号的不连续造成系统“颤动”问题；显示出模糊推理的作用。
According to the principle of sliding mode control, a fuzzy controller design method based on Lyapunov stability is derived for the un-modeled dynamic nonlinear system. The discontinuity of the control signal in the conventional nonlinear sliding mode control is caused by the system “chattering ”Problem; shows the role of fuzzy reasoning.
