Decentralized event-triggered control for sampled-data systems with asynchronous sampling

This paper proposes a new decentralized event-triggered communication scheme based on asynchronous sampling. The event-triggered communication scheme does not depend on the full-order state of the system. Several spatially distributed sensor nodes are employed to collect the state data. Each node transmits the samples according to a sub-communication scheme. An L₂ controller design method is developed for the decentralized event-triggered control system, which can be used to codesign of the decentralized event-triggered communication scheme and L₂ controller. A numerical example illustrates the merit and effectiveness of the proposed approach.
