摘要：
This paper proposes an event-triggered adaptive control scheme for switched nonlinear interconnected systems with unknown control coefficients and unknown backlash hys-teresis. Firstly, unknown interconnected terms and unknown nonlinearities of the system are approximated through fuzzy logic systems. By introducing the Nussbaum function and choosing an appropriate Lyapunov function, an event-triggered output feedback controller is developed. The proposed control scheme can guarantee that the whole states are semi -globally uniformly ultimately bounded, meanwhile, the elimination of Zeno behavior is en-sured. Eventually, the effectiveness of the method is verified by simulation results. (c) 2023 Elsevier Inc. All rights reserved.
