Abstract
This paper studies the decentralized event-triggered control of large-scale nonlinear systems. We consider a class of decentralized control systems that are transformable into an interconnection of input-to-state stable subsystems with the sampling errors as the inputs. The sampling events for each subsystem are triggered by a threshold signal, and the threshold signals for the subsystems are independent with each other for the decentralized implementation. By appropriately designing the event-triggering mechanisms, it is shown that infinitely fast sampling can be avoided for each subsystem and asymptotic regulation is achievable for the large-scale system. The proposed design is based on the ISS small-gain arguments, and is validated by a benchmark example of controlling two coupled inverted pendulums.
