摘要 研究了含不确定性线性奇异滞后系统的鲁棒H∞控制问题.其中不确定性是范数有界的.为此首先给出了相应的无控制标称系统内稳定且满足H∞范数界的一个充分条件.然后讨论了含不确定性奇异滞后系统鲁棒H∞控制问题有解的一个充分条件,并同时给出了控制器的设计,控制器可由线性矩阵不等式解得.最后举例说明本文方法的正确性. This paper examines the problem of robust H-infinity control for linear singular state delayed systems with norm-bounded parameter uncertainty. First, one sufficient algebraic condition is given to guarantee the stability and H-infinity norm-boundness of the corresponding unforced nominal singular systems with delay in state. Then, the sufficient condition is obtained for the existence of robust H-infinity controller using the method of LMI. The controller can be solved by two LMIs. Finally, an illustrative example is presented.
