Research of Robust Fault-Tolerant Control for T-S Fuzzy Time-Delays Descriptor System

Abstract:

In order to describe the time-delays and faults on continuous nonlinear descriptor system using T-S fuzzy model, an observer is proposed to estimate system states, actuator and sensor faults. A fuzzy state feedback controller is constructed for faults compensations. On the basic of Lyapunov stability theory, the proposed robust fault-tolerant control method ensures the closed-loop system to be robust stability even as faults occur. The actuator and sensor faults can be diagnosed and estimated in 0.2 seconds. The performance of the proposed design method is effective in simulations.
