论文摘要
在这项工作中，如果在不确定的平衡条件下进行操作，则考虑了DC-DC增强转换器的切换控制设计的问题，这是由于输入和负载参数的扰动而引起的。假设这些不确定的参数是通过已知的线性EXO系统生成的，则旨在实时更新开关控制器的平衡点。为了减轻与设计参数估计器相关的噪声放大问题，通过一组一阶过滤器过滤估计误差注射项，以在最终的估计值集中获得所需的噪声抑制水平。为了证明开发方案的效率，考虑到电动汽车的直流充电站的现实应用方案，并以光伏阵列为源，并且在负载侧连接了电池。
In this work, the problem of switching control design for DC-DC boost converter is considered, in the case of operation under uncertain equilibrium condition arising due to perturbations in the input and load parameters. Assuming that these uncertain parameters are generated via a known linear exo-system, a parameter estimator is designed to update the equilibrium point for the switching controller in real-time. In order to mitigate the noise amplification problem associated with the designed parameter estimator, the estimation error injection term is filtered via a set of first-order filters to obtain the desired level of noise suppression in the final set of estimates. To demonstrate the efficiency of the developed scheme, a realistic application scenario of a DC charging station for electric vehicles is considered, with photovoltaic array as the source and a battery connected at the load side.
