Abstract

This paper introduces two improved control algorithms for DC-DC converters. The first one is called “Non-Adaptive Modified Back-Stepping Control” (M-BSC) and the second one is called “Adaptive Modified Back-Stepping Control” (AM-BSC). Both the proposed control schemes allow one to increase the robustness to load and input voltage variations and make the DC-DC converter less sensitive to disturbances concerning the control algorithms available in the literature. The control aims to keep the output voltage at the desired value despite any changes that may occur during its operation. As a case study, the proposed control techniques have been applied to a DC-DC Buck converter. To validate the theoretical results and evaluate the performance of the proposed control algorithms, numerical simulations with four different scenarios have been analyzed: nominal operating conditions, load variations, output voltage tracking, and input voltage variations. The simulation results highlight the good performance of the proposed control algorithms compared to other classical algorithms, improving both the stationary error and the response time.

基于改进反步法的DC-DC降压变换器鲁棒非线性控制器设计

本文介绍了两种改进的DC-DC变换器控制算法。第一种是“非自适应修正后步控制”(M-BSC)，第二种是“自适应修正后步控制”(AM-BSC)。所提出的两种控制方案都允许人们增加对负载和输入电压变化的鲁棒性，并使DC-DC转换器对文献中可用的控制算法的干扰不那么敏感。控制的目的是保持输出电压在期望的值，尽管在其操作过程中可能发生任何变化。作为一个案例研究，所提出的控制技术已应用于DC-DC降压变换器。为了验证理论结果并评估所提出的控制算法的性能，我们分析了四种不同场景的数值模拟:标称运行条件、负载变化、输出电压跟踪和输入电压变化。仿真结果表明，与其他经典控制算法相比，所提出的控制算法具有良好的性能，在平稳误差和响应时间上都有所改善。
