Adaptive Decentralized Event-triggered Tracking Control for Large-scale Strongly Interconnected Nonlinear System with Global Performance

Wenjing Yang, Jianwei Xia*, Xiaoxiao Guo, Miao Yu, and Na Zhang

Abstract

In this paper, an adaptive decentralized event-triggered global performance control of a class of largescale strongly interconnected nonlinear systems with external disturbances is investigated. Firstly, the original performance constrained large-scale nonlinear system is transformed into an equivalent unconstrained nonlinear largescale system by barrier function transformation. Secondly, the additional assumptions of interconnect terms such as upper bound function and matching conditions are eliminated by using the inherent properties of Gaussian function. In addition, an event-triggered mechanism is designed to reduce unnecessary transfers between the controller and the actuator for better resource efficiency. It is shown that the proposed control schemes guarantee that all signals of the closed-loop system are bounded, and the output tracking error is always kept within the given boundary. Finally, a numerical system and a mass-spring damping system are taken as examples to verify the effectiveness of the proposed control method.

Keywords Decentralized control, event-triggered control, large-scale nonlinear systems, prescribed performance.
