Switched Control of DC/DC Converter Based on Hybrid Model

A Switched Boost converter controller is designed based on the piecewise linear model and static average model. At the beginning of the response, a min-projection-controller is adopted to get satisfying transient performance. At the end of the transient, a PWM controller switches in to reduce the working frequency of the closed-loop system. Synchronization of control signals can avoid disturbances during switching. Simulation results testify the control effect of the switched controller.
