Abstract
This paper studies the problem of adaptive event-triggered dynamic output feedback fuzzy control for nonlinear networked control systems (NCSs). Two crucial factors, packet dropouts and random actuator failure, are taken into consideration simultaneously. Takagi-Sugeno (T-S) fuzzy model is introduced to describe considered systems. The Bernoulli random distribution process is employed to depict the phenomenon of data missing. A stochastic function, which is related to Markovian variables, is adopted to depict the actuator failure. An innovative adaptive event-triggered mechanism is introduced to save computational resource. In the framework of Lyapunov stability theory, an adaptive event-triggered fuzzy dynamic output feedback controller is designed to guarantee the stochastic stability and <formula><tex>$\mathcal{H}_{\infty}$</tex></formula> performance for considered systems. Finally, simulation results are provided to demonstrate the usefulness of the proposed control strategy.
