基于频域方法时滞系统H~∞控制的新结果(英文)

Recent results on H~∞ control of time-delay systems using frequency-domain approaches

时滞系统多出现在工程实践中,如通信网络、化工过程、远程手术系统等.时滞的存在使系统的分析和控制设计更为复杂.本文总结了作者在时滞系统H∞控制方面的研究成果,主要内容包括标准H∞控制问题、时滞型Nehari问题和控制器参数化及控制器实现等,并提出了今后有待研究的一些问题.

Systems with delays frequently appear in engineering. Typical examples of time-delay systems are communication networks, chemical processes, and tete-operation systems. The presence of delays makes system analysis and control design much more complicated. In this survey paper, some of the recent results obtained by the author on H∞ control of time-delay systems were summarized. The problems discussed include the standard H∞ control problem, the delay-type Nehari problem, controller parametrisation and controller implementation. Some problems for future research were highlighted.
