| 摘 要： | 针对一类非线性不确定时滞系统,分别考虑了观测器的设计和控制器的设计问题.首先,基于扩张状态方程,设计鲁棒观测器；其次,基于观测器估计的状态值,融合H∞控制技术,设计了滑模控制器,并且将滑模控制器增益系数的计算问题转化为线性矩阵不等式的求解问题,而且所设计的滑模控制器不要求系统不确定项满足匹配条件,使得控制器具有广泛的使用范围；最后,给出数值算例,将设计的观测器和控制器应用算例中,仿真表明该方法的有效性. |

| Abstract: | According to a class of uncertain time-delay system,the observer and the sliding mode controller are considered respectively.Firstly,the robust observer is disigned based on the expansion state equation;secondly,the sliding mode controller is designed by using the estimated value and the technique,and the computation of the sliding mode gain are transferred into the solution of the linear matrix inequality.However,the designed sliding mode controller are used widly without demanding the matching condition;at last,the numerical example is simulated taking advantage of the observer and the controler,which prove the effec. |
