有未知延迟的下三角系统的输出反馈控制

主要研究状态和输入都有未知时变延迟的下三角系统的输出反馈控制.关于延迟仅规定它是有界的,但它的边界和时变率是未知的.针对要研究的系统,首先提出一个新的自适应输出反馈控制器;然后,为了处理有未知时变的状态,给出了一个新的变换和技术;最后,说明在所给的输出反馈控制器下所研究的系统是全局可控的.仿真结果说明了控制器的有效性.

Output feedback regulation of lower triangular system with unknown time-varying delays

The output feedback control of a lower triangular system with unknown time-varying delays in both states and input have been studied in this paper.The time-varying delays are only known to be bounded,and their bounds and time-varying rates are unknown.First,a newly designed adaptive output feedback controller is proposed in this note.Then,in order to deal with new phenomena associated with unknown time-varying delays in states,we give a new transformation and techniques.Finally,the system is globally regulated by the output feedback controller.A simulation example shows the effectiveness of the controller.
