Ali Parsa Sirat, Niloofar Zendehdel

摘要:

本文提出了一种基于开关控制器的DC-DC降压变换器的最优控制方法。结果表明,传统的控制器技术的DC-DC转换器的线性化平均模型的基础上有几个缺点,包括不同的操作模式,线性化的关注,和约束困难。采用单模态离散化状态空间模型,提出了一种新的最优逼近策略来控制降压型DC-DC变换器。仿真结果表明,所提出的DC-DC模型与最优控制器相结合,能够有效地控制DC-DC非固定开关模式降压变换器在负载变化、噪声输入和启动过程中的运行。

英文摘要:

In this paper, an optimal approach based on on-off controller is used to optimally control a DC-DC step-down converter. It is shown that the conventional controller techniques of DC-DC converters based on a linearized averaging model have several drawbacks, including different operating mode, linearization concerns, and constraint difficulties. A single-mode discretize state-space model is used, and a new optimal approach policy is implemented to control a step-down DC-DC converter. The simulation results confirm that the proposed DC-DC model associated with the optimal controller functions properly in controlling a DC-DC unfixed switch-mode step-down converter that is facing load changes, noisy inputs, and start-up procedure.
