| 摘 要： | 考虑了不确定仿射非线性系统的鲁棒耗散性与保性能控制问题,不确定性范数有界,不满足匹配条件.基于HJI不等式,设计了状态反馈控制器.当扰动存在时,控制器能使系统达到耗散,当扰动为零时,所设计的控制器使系统对于给定的性能函数具有上界,最后研究了不确定线性系统的保性能与耗散性控制情形.

| Abstract: | The problem of robust dissipative control and guaranteed cost control for uncertain nonlinear systems was considered. The uncertainties were norm bounded, and did not satisfy matching conditions. Based on HJI, a state feedback controller was constructed which rendered the closed-loop system dissipative when there existed disturbances in systems, and also guaranteed the given cost bounded for the closed-loop system without the disturbances in systems. Finally, robust dissipative was investigated and control problem for uncertain linear systems was guaranteed. |
