摘要： 在实践应用过程中,控制元件(包括执行器或传感器)的失效往往会造成系统不稳定或性能指标难以达到·因此研究如何利用仅存的有效控制元件来实现控制目标十分必要·由此"可靠控制"应运而生,即无论特定集合中的某些控制元器件失效与否,都要求所设计的控制器能保证系统的稳定性和各项性能指标的实现·针对执行器失效的线性广义系统,给出可靠最优调节器设计方法,所设计的状态反馈控制器能够使执行器故障系统具有正则、渐近稳定、无脉冲,且此时的二次性能指标小于正常情况下的二次性能指标·

Abstract: Failures of the control components (actuators and sensors) in practice usually results in the unstability of a control system or can not attain the desired performance. Therefore, it is very important to investigate how to achieve the control goal using scanty effective control components. Whether some of the control components in the measurement set are invalid or not the reliable problem is about designing a controller to guarantee the stability and all the desired control performance. A design method of reliable linear quadratic state feedback controller for linear descriptor systems with actuator failure is presented. The designed state feedback controller guarantees systems regular, asymptotically stable and impulse-free against the actuator failure.
