一类非线性时滞系统的鲁棒可靠控制

Robust Reliable Control for a Class of State Delay Nonlinear Systems

基于系统传感器与执行器同时出现失误的情况,对不确定时滞系统进行可靠性设计,使得所设计的系统不仅在系统运行良好的情况下,而且在出现多种失误的条件下仍然能正常运行。基于Riccati不等式正定解的存在性,给出了基于观测器的动态输出反馈可靠控制器的设计方案。最后,以一个数值仿真例子进一步说明设计步骤,以及文中所提出的设计方法的有效性。

This paper focusos on the reliable control for a class of nonlinear uncertain state delay systems. The purpose of this paper is to design a reliable controller such that the closed-loop system remains asymptotically stable for all admissible uncertainties independently of the time delay,not only when the system is operating properly,but also when there exist a simultaneous presence of actuator and sensor failures An effective,modified algebraic Riccati matrix inequality approach is developed to solve the problem addressed. Finally,an numerical example is given to demonstrate the applicability and effectiveness of the design approach proposed in this paper.
