摘要

In the context of an event-based control paradigm, when the controller-to-plant channels are subject to event-driven time sampling, a new scheme of feedback model reference adaptive control is developed. The developed scheme can cope with multiple distinct input and state time delays in the dynamics description and mitigate the effect of uncertainties due to both the traditional and network-induced phenomena. The underlying idea is based on a suitable equivalent reformulation of the plant model. In this way, it is possible to pull the input delay out of the design control law. The synthesized controller is demonstrated by applying it to perimeter urban traffic control.
