| 摘 要： | 时滞是自然界中广泛存在而又不可避免的一种现象。研究时滞现象,对于解决工程中的时延问题,提高控制系统性能,有着理论和实践意义。时滞控制基于内模原理,在控制器中引入时滞项以减少额外的干扰,从而提高控制系统的性能。本文概述了时滞控制理论的最新研究进展,包括:(1)时滞控制系统的数学模型及其分类,系统的鲁棒性与稳定性分析,最优与次优控制等;(2)时滞控制的基本原理与研究现状,时滞控制与其他控制方法的结合情况。最后指出了时滞控制系统需要进一步研究和解决的几个主要问题,并对其未来发展方向做了展望。

| Abstract: | Time-delay is a phenomenon of nature,and it exists widely and cannot be avoided.It is very important to study the phenomenon in resolving the retard in engineering and improving the performances of control system.Based on the internal mode theory,time-delay control introduces a small delay in the control design to reduce the effect of additive disturbances and to improve the system performances.In this paper,recent advances of time-delay control system are summarized firstly,including:(1) the mathematical model of time-delay control system and its classification,the system's robustness and the stability analysis,the optimal control and the sub-optimal control,etc;(2) the principle and present advances of time-delay control,the combination of time-delay control with other control methods.Some unsolved questions are discussed and the future tendency of time-delay control system is presented. |
