| 摘 要： | 研究了一类输入饱和T-S 模糊系统的扰动抑制问题。采用分区讨论与大中取大综合方法处理饱和项，利用Lyapunov 稳定性理论，提出了非线性系统的执行器饱和控制器存在的充分条件，进一步对控制器进行了优化，以实现扰动抑制要求。通过简单变换，将该条件转化为Matlab 易于求解的线性矩阵不等式。最后对鲁里叶(Lurie)系统的控制仿真验证了方法的有效性。

| Abstract: | The problem of disturbance attenuation to T-S fuzzy system with input saturation is studied. Using the method of zoned discussion and maximax synthesis to deal with the saturation term, a sufficient condition for the existence of the controller with input saturation is presented，and the optimization of the controller is discussed to realize disturbance attenuation to the nonlinear system under the Lyapunov stability theory. After some easy transformation, the condition is turned into linear matrix inequalities (LMIs) form which is easy to solve by the help of Matlab. Simulations of the control to Lurier system show the effectiveness of the proposed method. |
