Event-Triggered PI Control of Buck Converter in Cyber-Physical Framework

Abstract

This paper presents the voltage control of a DC-DC buck converter connected in a cyber-physical space using an event-triggered PI controller. The communication between the cyber layer and the plant is invoked whenever a threshold condition is violated. The Lyapunov stability of the closed-loop system is established along with a Zeno free behaviour. Finally, the proposed control scheme is applied to a practical system to verify its effectiveness.
