时滞不确定系统静态输出反馈可靠控制

Static Output Feedback Reliable Control of Uncertain Systems with Time-Delay

针对时滞不确定线性系统,提出了具有执行器故障的静态输出反馈控制问题.首先给出了系统无故障时设计控制器使系统保持渐近稳定的充分条件;然后讨论了对于同一系统同一控制器在执行器发生故障时系统出现不稳定的情况;下一步,针对同一故障模型重新设计静态输出反馈控制器使系统在发生故障后仍保持渐近稳定;最后,数值仿真验证了结果的有效性.

For linear systems of uncertainties with time-delay,this writer proposes the problem of a static output feedback control with actuator failure. Firstly,a sufficient condition of asymptotic stability is presented when the fault is not considered in designing the controller. Then we discuss the system is not stable when the fault occurs for the same system and controller. Next,for the same fault model redesign static output feedback controller supposing the system remains asymptotically stable after the fault occurs. A simulation example is given to illustrate the feasibility and effectiveness of the results.
