Fuzzy adaptive event-triggered finite-time constraint control for output-feedback uncertain nonlinear systems

A fuzzy adaptive event-triggered finite-time constraint control for the uncertain nonlinear system with input hysteresis is developed. Input hysteresis, uncertain and nonlinear characteristic, widely existing in the actual control system, which seriously affect the performance and convergence time of control system. Thus, a fuzzy adaptive event-triggered control method is constructed to overcome the above issues under the limited communication recourses. Furthermore, to ensure the system converges in finite time, an event-triggered finite-time control method is proposed where the communication resources are limited. Finally, some simulation experiments verify the system converges in finite time and the bandwidth resources can be effectively saved under the proposed method. (C) 2021 Elsevier B.V.
