不确定线性时滞系统的H_∞控制

H_∞ Control for Uncertain Linear Time-delay Systems

研究了一类含有不确定参数的线性时滞系统的H∞控制问题,所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.通过加零项使所得结果具有更弱的保守性.数值例子和仿真证明了所设计控制器的有效性和可行性.

Considering the H∞ control problem for a class of uncertain linear time-delay systems. For all admissible uncertainties and delays, the desgined controller can guaranteed that the closed-loop system is asymptotically stable and closedloop has prescribed H∞ performance level. By adding zero term, there is more conservative in the results. A numerial example and simulations results verify the effectiveness and feasible of the desgined controller.
