Delay-dependent Integrity Conditions for Networked Control System Based on Takagi Sugeno Fuzzy Model
The problem of fault-tolerant control for a class of nonlinear networked control systems (NCSs) is investigated in this paper. AT-S fuzzy model is employed to represent the nonlinear controlled plant in the NCSs. Both networked-induced delay and packet dropout in transmission are addressed. By using LyapunovKrasovskii functional, the less conservative integrity condition for NCSs with failures of actuator and sensor is given based on a delay-dependent approach, and the fault-tolerant controller gain can be obtained via solving several linear matrix inequalities (LMIs). Moreover, some slack matrices which reduce conservatism are introduced during the proof. Finally, an example is used to illustrate the effectiveness and the feasibility of the proposed approach.
