Event-Triggered Control for DC-DC Boost Converters

An event-triggered control scheme is presented in this paper for a DC-DC boost converter. In this scheme, the control signal is only triggered when the converter state exceeds a preset threshold otherwise the scheme is not engaged, and the control signal remains constant. Thus, compared with the conventional control techniques, the event-triggered method has the advantage of requiring less computation time, which enhances the regulatory performance. The control scheme is derived from the Lyapunov stability theorem, which leads to linear matrix inequality (LMI), and these LMI is shown to be feasible. We also demonstrated that the Zeno behavior is ruled out by imposing a lower bound by positive constant on the inter-event time. The performance of proposed event-triggered control is illustrated through a boost converter prototype.
