Popis
Shrnutí:This paper studies the fuzzy decentralized output feedback event-triggered control problem for the interval type–2 Takagi-Sugeno (IT2 T-S) fuzzy interconnected system with actuator saturation. Firstly, a state decentralized observer is designed and an event-triggered mechanism is established by using the state estimation errors. Secondly, the saturated inputs are represented by a polyhedron model, and then a fuzzy decentralized output feedback even-triggered control approach is developed via the parallel distributed compensation (PDC) algorithm. The asymptotic stabilization sufficient conditions of the closed-loop system are derived by employing Lyapunov theory and linear matrix inequalities (LMIs) method. Finally, a numerical example is provided to verify the feasibility of the developed control scheme.
