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。 Based on the simultaneous errors of system sensors and actuators, the reliability design of uncertain time-delay system is carried out so that the designed system can operate normally not only under the condition of good system operation but also under various mistakes . Based on the existence of positive definite solution of Riccati inequality, a design scheme of observer-based dynamic output feedback controller is presented. Finally, a numerical simulation example is used to illustrate the design procedure and the validity of the design method proposed in this paper.
