SOME PROBLEMS OF DELAYED FEEDBACK CONTROL

近几十年来,时滞系统动力学的研究得到了众多学者的大量关注,研究者在时滞系统的稳定性、非线性、辨识、时滞消除与利用技术等方面做了大量研究,取得了许多成果.本文主要介绍作者十多年来在时滞系统动力学方面的研究成果,包括时滞辨识、两种基于时滞方程的控制律的设计方法、时滞鲁棒控制律的设计、时滞正反馈控制技术、非线性结构时滞控制律的设计、时滞实验等内容.

In recent decades, the studies on delayed system dynamics has been getting more and more atten- tions. Many researches have been done on the stability, nonlinearity, delay identification, delay compensation and delay utilization of time-delay systems. This paper outlines some advances in the authors＇ studies on time delay problems in recent years, including delay identification, two delay controllers based on time-delay dy- namical equation, robust delay controller, delayed positive feedback technique, controller design for nonlinear time-delay structures and time delay experiments.
