Event-triggered control of nonlinear systems from data
For control engineers, it offers a data-driven method to design event-triggered controllers for nonlinear systems without a model, but the extension is incremental.
This paper extends a data-based event-triggered control approach from linear to a class of nonlinear systems, providing two Lyapunov-certified designs with tuned parameters that ensure a positive minimum inter-event time.
In a recent paper [8], we introduced a data-based approach to design event-triggered controllers for linear systems directly from data. Here, we extend the results in [8] to a class of nonlinear systems. We provide two data-based designs certified by a (classical) Lyapunov function. For these two designs, we devise event-triggered policies that rely on the previously found Lyapunov function, have parameters tuned from data, ensure a positive minimum inter-event time, and act based either on the state error or on the library error. These two different policies, and their respective advantages, are illustrated numerically.
