| 中文摘要 |
| 针对一类具有范数有界不确定性和时变时滞的It^o型随机Lurie系统, 研究了鲁棒H∞和L2–L∞指数控制问题. 利用Lyapunov-Krasovskii泛函方法和It^o微分公式, 得到了以线性矩阵不等式(LMIs)表示的控制器存在的充分条件. 对所有容许的参数不确定性, 设计的无记忆状态反馈控制器使闭环系统鲁棒指数均方稳定, 且具有给定的H∞和L2–L∞干扰抑制度. 最后, 通过两个仿真例子说明了所提方法的有效性. |
| 英文摘要 |
| The robust exponential H-infinity control and the exponential L-two-L-infinity control for a class of uncertain It^o-type stochastic Lurie systems with time-delay are investigated. The uncertainties are norm-bounded and the delays are time-varying. Based on Lyapunov-Krasovskii functional method and It^o differential formula, we formulate the sufficient conditions for the existence of desired controllers in terms of linear matrix inequalities(LMIs). For all admissible uncertainties, the designed memoryless state-feedback controllers ensure that the closed-loop systems are robustly exponentially mean-square stable with prescribed H-infinity and L-two-L-infinity disturbance attenuation levels. Finally, the effectiveness of the proposed methods is demonstrated by two simulation examples. |
