Robust Fault-tolerant Control for Time-Varying Descriptor System

摘要

In this paper, a class of time-varying descriptor system with uncertain parameters is investigated based on the analysis method of linear matrix inequality. By constructing Lyapunov functions, the problems of robust stabilization for the system are analysed, and sufficient conditions of robust stabilization are obtained. When actuator failure occurs, the robust fault-tolerant control for the system is also discussed, considering the cases where the state vector can be fully observed and cannot be directly observed.
