摘要

本文提出了一种有限控制集模型预测控制(FCS-MPC)方法来控制电池充电器用双向dc-dc变换器。利用输入电压、输出电压和输出功率估算双向dc-dc变换器升压模式下的电感基准电流,从而控制直流母线电压。电池通过恒流(CC)和恒压(CV)控制方式充电。主要控制目标是:1)通过从电池向直流母线供电,将直流母线电压调节到参考值,2)使用电流控制使电池放电,以及3)用直流母线的CC和CV给电池充电。通过MATLAB/simulink对该控制算法进行了验证。

Model Predictive Control of Bi-directional dc-dc Converter for Battery Charger Application
This paper presents a finite control set model predictive control (FCS-MPC) approach to control bi-directional dc-dc converter for battery charger application. The dc bus voltage is controlled by estimating the inductor current reference in boost mode of bi-directional dc-dc converter using the input voltage, output voltage, and output power. The battery is charged by constant current (CC) and constant voltage (CV) control methods. The main control objectives are: 1) regulation of the dc bus voltage at a reference value by supplying the power to the dc bus from the battery, 2) discharging the battery using current control, and 3) charge the battery with CC and CV from the dc bus. This control algorithm is verified via MATLAB/simulink.
