TLDR
An event-triggering scheme, where a subsystem broadcasts its state information to its neighbors only when the subsystem's local state error exceeds a specified threshold, which means the resulting system is globally uniformly ultimately bounded using this scheme.Abstract:
This paper studies distributed networked systems with data dropouts and transmission delays. We propose an event-triggering scheme, where a subsystem broadcasts its state information to its neighbors only when the subsystem's local state error exceeds a specified threshold. This scheme is completely decentralized, which means that a subsystem's broadcast decisions are made using its local sampled data, the maximal allowable transmission delay of a subsystem's broadcast is predicted based on the local information, a subsystem locally identifies the maximal allowable number of its successive data dropouts, and the designer's selection of the threshold only requires information about an individual subsystem and its immediate neighbors. With the assumption that the number of each subsystem's successive data dropouts is less than the bound identified by that subsystem, if the bandwidth of the network is limited so that the transmission delays are always greater than a positive constant, the resulting system is globally uniformly ultimately bounded using our scheme; otherwise, the resulting system is asymptotically stable.read more

Brief paper: A state-feedback approach to event-based control

TL;DR: An upper bound of the difference between both loops is derived, which shows that the approximation of the continuous state-feedback loop by the event-based control loop can be made arbitrarily tight by appropriately choosing the threshold parameter of the event generator.

Event-Triggered Real-Time Scheduling of Stabilizing Control Tasks
TL;DR: This note investigates a simple event-triggered scheduler based on the paradigm that a real-time scheduler could be regarded as a feedback controller that decides which task is executed at any given instant and shows how it leads to guaranteed performance thus relaxing the more traditional periodic execution requirements.

Stability analysis of networked control systems
TL;DR: A novel control network protocol, try-once-discard (TOD), is introduced for multiple-input-multiple-output (MIMO) networked control systems (NCSs), and an analytic proof of global exponential stability is provided for both the new protocol and the more commonly used (statically scheduled) access methods.

Systems with finite communication bandwidth constraints. II. Stabilization with limited information feedback
TL;DR: A new class of feedback control problems is introduced, which cannot be asymptotically stabilized if the underlying dynamics are unstable, and a weaker stability concept called containability is introduced.
