Abstract This paper deals with a control strategy for a DC–DC quadratic boost converter. In particular, a hybrid control scheme is proposed to encompass a control law and an observer for the estimation of the system states, based only on the measurements of the input and output voltages. Differently from classical control methods, where the controller is designed from a small-signal model, here the real model of the system is examined without considering the average values of the discrete variables. Using hybrid dynamical system theory, asymptotic stability of a neighborhood of the equilibrium point is established, ensuring practical stability of the origin, which contains estimation and tracking errors. Experimental results show the effectiveness of the proposed approach.

具有电感电流估计的二次升压转换器的混合控制策略

摘要 本文涉及 DC-DC 二次升压转换器的控制策略。特别是，提出了一种混合控制方案，以包含控制律和用于估计系统状态的观察器，仅基于输入和输出电压的测量。与从小信号模型设计控制器的经典控制方法不同，这里检查系统的真实模型而不考虑离散变量的平均值。利用混合动力系统理论，建立了平衡点邻域的渐近稳定性，保证了包含估计和跟踪误差的原点的实际稳定性。实验结果表明了所提出方法的有效性。
