【摘要】 针对传感器失效的时滞系统,利用时滞系统的H∞理论和状态观测器理论给出具有完整性控制器的设计方法, 设计的基于观测器的反馈控制器不仅使正常闭环系统稳定保持一定的H∞性能指标,而且使传感器失效的闭环系统也是稳定的,同时保持H∞性能指标．数值例子验证了所提方法的有效性。更多还原

【Abstract】 Based on H∞ theory and state-observer theory in time-delay systems, a method of designing controllers for time-delay systems with sensor failures is presented. The controller designed by the proposed method can guarantee the stability of the resultant closed-loop systems and keep certain H∞, norm performance in the normal condition as well as in the event of sensor failures. A numerical example shows the validity of the proposed approach.更多还原
