一类线性不确定系统H_∞鲁棒可靠观测器、控制器的设计

H_∞ robust reliable observer and controller design for a linear systems with uncertainty

主要研究了一类线性不确定系统的基于观测器的H∞鲁棒可控制问题.在LMI方法的基础上给出了经估计H∞鲁棒可靠控制的设计方案,使设计的闭环系统能对所有允许的不确定性及对指定执行器子集合中的任意执行器失效时,仍能保持具有H∞范数界的二次稳定,并通过仿真验证了结果的正确性和有效性.

This paper studies the problem ofobserver-based H_∞ robust and reliable control for linear systems with uncertainty.An estimated H_∞ robust and reliable control design scheme is presented by means of linear matrix inequality (LMI) such that the corresponding closed-loop system can keep quadratic stability with and H_∞ -norm bound for all admissible uncertainties and actuator failure occurring in a prespcified subset of actuators.And a simulated example is given to demonstrate the effectiveness of the approach presented in this paper.
