摘 要: 讨论一类具有参数不确定性的状态时滞和具有外部干扰的线性广义系统的鲁棒H∞控制问题.不确定性假设是范数有界的,采用线性矩阵不等式处理方法,得到不确定时滞相关稳定性的充分条件.给出在静态输出反馈情况下的控制器设计方法,使得闭环系统是正则、无脉冲和稳定的,并且满足给定的H∞性能指标.控制器可由一组线性矩阵不等式(LM I)求解.给出的数值算例说明了该方法的有效性. The problem of parametric uncertainties and external disturbance robust H∞ control for a class of linear singular systems with time delay is discussed. Parametric uncetainty is assumed to be norm bounded. Delay-dependent uncertain parametric sufficient conditions are obtained by using the linear matrix inequality method, and a method of designing controllers under output feedback conditions is given. The closed-loop systems is not only regular, impulse-free and stable, but also it satisfis a prescribed H∞ performance criterion. The controller can be constructed in terms of the linear-matrix inequalities (LMI). Finally, a numercial example shows the effectiveness of the method.
