Output voltage control of DC-DC boost converter using model predictive control approach

Abstract

This article contains an approach to control the output voltage of dc-dc boost converter using model predictive control algorithm. State space modeling of a boost converter is done for both continuous and discontinuous conduction mode. By implementing online optimization and constraint satisfaction it produces a control input which regulates the output terminal voltage to its given reference. Disturbances produced due to load variation at output terminal are taken care of by an observer which is implemented by using kalman state estimator. Simulations are carried out on Simulink-MATLAB platform to examine the merits of proposed strategy, which includes fast transient response and robustness. � 2018 IEEE.
