Disturbance Observer-based H∞ Control for Interval Type-2 T-S Fuzzy Systems With An Event-triggered Communication

This paper deals with the asynchronous fuzzy H ∞ control for nonlinear network control systems with network-induced delays, exogenous signal disturbances, and asynchronous premise variables. This system is represented by the interval type-2 Takagi-Sugeno (IT2 T-S) fuzzy model. An asynchronous disturbance observer is designed to estimate the system states and the disturbances simultaneously. In addition, an event-triggered communication (ETC) is developed to reduce network costs. Finally, the feasibility of DO and fuzzy controllers is verified by numerical simulation.
