Adaptive control for the nonlinear event-triggered networked control system: a decoupling method

چکیده
In this paper, the adaptive control for a kind of nonlinear system over event-driven sensors-controller communication network is addressed. Over network, existing strategy has been developed. However, event-triggered mechanism and estimators are coupled together, which results in extra information delivery or computation equipment on sensor side. To overcome limitations, two kinds strategies proposed paper. At first, with new estimator developed without external disturbances where does not need estimators. It proved that closed-loop asymptotically stable Zeno behaviour excluded. Furthermore, disturbances, robust scheme modified practical stability guaranteed. Also, excluded carefully. Comparing results, due to decoupling structure estimators, it unnecessary transfer estimators’ side, saves cost. What’s more, although state sampled event driven, asymptotical still can handle disturbances. Finally, examples performed illustrate effectiveness schemes some comparisons displayed explain advantages methods.

Event-Triggered Networked Control Systems
Many of the results for event-triggered control of embedded systems can be extended to networked control systems. A networked control system or NCS is a set of controllers that coordinate their actions over a communication network. For NCS, event-triggering is used to decide when to transmit or broadcast the system state to a local controller’s neighbors. Using events to trigger communication a...
متن کاملL1 Adaptive Control of Event-Triggered Networked Systems
This paper studies the implementation of L1 adaptive controller over real-time networks using event-triggering. Event-triggering schedules the data transmission dependent upon errors exceeding certain threshold. We provide eventtriggering schemes to characterize the time instants of data transmissions, while using L1 adaptive controller in the feedback loop. Lower bounds on transmission periods...
متن کاملSuboptimal event-triggered control for networked control systems
The advent of networked control systems urges the digital control design to incorporate communication constraints efficiently. In order to accommodate this requirement, this article studies the joint design of controller and event-trigger for linear stochastic systems in the presence of a resource-limited communication channel which exhibits packet dropouts and time-delay. The event-trigger sit...
متن کاملEvent-triggered Learning for Resource-efficient Networked Control
Common event-triggered state estimation (ETSE) algorithms save communication in networked control systems by predicting agents’ behavior, and transmitting updates only when the predictions deviate significantly. The effectiveness in reducing communication thus heavily depends on the quality of the dynamics models used to predict the agents’ states or measurements. Event-triggered learning is pr...
