不确定时滞系统的鲁棒H_∞控制器设计

Robust H_∞Controller Design for Uncertain Time-delay Systems

针对一类含有不确定参数的线性时滞系统的控制问题,利用LMI方法研究了反馈控制器的分析与设计,设计的控制器对于所允许的参数不确定性和时滞,能保证闭环系统渐近稳定且闭环系统具有理想的性能指标,通过数值例子说明了所设计控制器的有效性和可行性。

This paper is concerned with the problem of analysising and designing the control of a class of uncertain linear time-delay systems by using the LMI approach.For alladmissible uncertainties and delays,the desgined controller can guarantee that the closed-loop system is asymptotically stable and closed-loop has prescribed performance level.A numerical example is given to show the effectiveness and feasible of the desgined controller.
