On the Problem of Quadratically Stability Fault-Tolrence Control for Multivariable Systems
多变量系统二次稳定性容错控制问题的研究

In this paper, some of mordern robust control theory are used to study the problems of quadratically stability fault-tolrence control for multivariable control systems.It is pointed out that the actuator or sensor failures can be considered as some type of structured uncertainties of the systems. On the basis of this viewpoint, assuming that there are failures on actuators, sensors or the both, the necessary and sufficient conditions are put forward for systems keeping quadratical stability.
