This paper describes a novel robust decentralized control design methodology for a single inductor multiple output (SIMO) DC-DC converter. Based on a nominal multiple input multiple output (MIMO) plant model and performance requirements, a pairing input-output analysis is performed to select the suitable input to control each output aiming to attenuate the loop coupling. Thus, the plant uncertainty limits are selected and expressed in interval form with parameter values of the plant model. A single inductor dual output (SIDO) DC-DC buck converter board is developed for experimental tests. The experimental results show that the proposed methodology can maintain a desirable performance even in the presence of parametric uncertainties. Furthermore, the performance indexes calculated from experimental data show that the proposed methodology outperforms classical MIMO control techniques.
本文提出了一种新颖的鲁棒分散式控制设计方法，用于单电感器多输出（SIMO）直流-直流转换器。基于标称多输入多输出（MIMO）植物模型和性能要求，进行配对输入-输出分析，以选择合适的输入来控制每个输出，旨在衰减环路耦合。因此，选择了植物不确定性极限，并以植物模型参数值的形式表示为区间形式。开发了单电感器双输出（SIDO）直流-直流降压转换器板进行实验测试。实验结果表明，即使在存在参数不确定性的情况下，所提出的方法也可以保持良好的性能。此外，从实验数据计算出的性能指标表明，所提出的方法优于经典的 MIMO 控制技术。
