非线性系统的模糊滑动模态控制

Fuzzy Sliding Mode Control of Nonlinear Systems

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。

Based on the sliding mode control(SMC) theory,a design method of fuzzy controller using Lyapunov stability theory is presented for the unmodeled nonlinear systems in this paper .The chattering problem in the existed SMC systems that the control signal occurs on\|off state for nonlinear systems can be avoided,and it shows the effect of fuzzy inference.
