摘要： 对于线性系统,研究了基于线性矩阵不等式的动态输出反馈可靠H∞控制器设计问题.在设计过程中,使用了比离散故障更实际的连续故障模型.不论有无故障,设计的可靠控制系统均保证了执行器的渐近稳定性和H∞性能.在保证故障发生时一个给定H∞性能界的前提下,优化无故障情况下系统的H∞性能.一个数值例子说明了提出方法的设计过程和有效性.

Abstract: Studied the reliable H∞ control design of dynamic output feedback control for linear systems on the basis of the linear matrix inequality (LMI). During the design a continuous fault model that is more practical than discrete fault one is developed. The reliable control systems designed can ensure the asymptotic stability and H∞ performance of an actuator in operation whether a fault happens or not. Under the conditions that an H∞ performance bound is given when a fault happens, the H∞ performance of a system is optimized in case no fault happens. A numerical example is also given to illustrate the design procedure and its effectiveness.
