Switched Controller Design for DC/DC Converter

摘要

A switched controller is designed for the Boost DC/DC converter. The proposed switched controller takes advantage of both min-projection-controller (MPC) and integral modulated pulse-width controller (IMPWC), in which the MPC deals with the transient process and the IMPWC is in charge of the steady state. Smooth switching is ensured by resetting the integral value of IMPWC according to the static average model and steady output voltage. Simulation results proved the control effect of the switched controller.
