摘　　要： 为有两变化时间的围住标准的参数无常和致动器失败的线性不明确的冲动的系统的柔韧、可靠的控制设计的问题被学习。致动器被分类进二个组。产生失败的致动器的一个集合是可能的失败，对失败柔韧的致动器的另外的集合被假定永不失败。致动器失败的产量被认为是零。目的是设计州的反馈控制器以便，为发生在致动器的一个 prespecified 子集之中的所有可被考虑的无常以及致动器失败，植物仍然保持 asymptotically 稳定。一条修改代数学的 Riccati 方程途径被开发解决处理的问题，一条柔韧的可靠控制法律被获得。一个数字例子也被提供证明建议方法的有效性。 The problem of robust and reliable control design for linear uncertain impulsive systems with both time-varying norm-bounded parameter uncertainty and actuator failures was studied. The actuators are classified into two groups. One set of actuators susceptible to failures is possible to fail, the other set of actuators robust to failures is assumed never to fail. The outputs of the actuator failures are regarded as zero. The purpose is to design the state feedback controller such that, for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the plant remains asymptotically stable. A modified algebraic Riccati equation approach was developed to solve the problem addressed and a robust reliable control law was obtained. An numerical example was also offered to prove the effectiveness of the proposed method.
