| 摘 要： | 研究了一类非线性系统的模糊变结构控制问题，并给出了稳定性证明。通过将非线性系统化为多个精确T—S模型来建立非线性系统精确的T—S模糊模型，将模糊理论与成熟的线性变结构控制理论相结合设计一种模糊变结构控制器，用Lyapunov稳定性理论证明该控制器能确保模糊动态模型全局渐近稳定，从而使非线性系统稳定。仿真结果表明了该设计方法的有效性。

| Abstract: | The fuzzy variable structure control of a kind of non li near system is studied by using T-S fuzzy model,and this kind of controller is proved to be steady.The T-S fuzzy model of a nonlinear system is structured b y several ex-act T-S fuzzy models of nonlinear system,the fuzzy variable stru cture controller is designed by combining fuzzy theo-ry with mature linear vari able structure theory,and the controller can make fuzzy dynamic model be global ly asymp-totically stable,thus nonlinear system is stable.Simulation rusults show the validity of the design mothod. |
