摘要
首先讨论了非受限区间广义系统的容许性问题 ,用广义 Riccati不等式给出该系统容许的充要条件 ;再讨论了区间广义系统的鲁棒控制问题 ,并且用广义 Riccati不等式给出状态反馈下的闭环系统容许且传递函数矩阵的 H∞ 范数小于给定的正常数γ的充分条件 。
In this paper, firstly ,the problem of admissiblity about unforced descriptor systems is discussed. A sufficient and necessary condition is presented. Secondly the problem of H ∞ robust control of interval descriptor systems is considered. A sufficient condition via the state feedback is derived by the method of generalized Riccati inequality, under which the closed loop system is admissible and the H ∞ norm of transfer function matrix less than a given positive constant γ.
