Abstract

Boost converters are key components of DC power conversion used for electric mobility and renewable energy applications. In addition to constant voltage control of the output, variable voltage control has been attracting attention in recent years for high-efficiency drive of loads. However, the dynamic characteristics of boost converters exhibit non- linear and nonminimum phase characteristics. Therefore, the inverse model for feedforward control is unstable, making high-precision voltage trajectory tracking control challenging. This study aims to present a noncausal and nonlinear feedforward controller to compensate for the nonlinear and nonminimum phase characteristics of the boost converter and to achieve perfect tracking control with respect to the output voltage trajectory. This study also establishes a method for identifying circuit parameters and deriving the time length of noncausal control input for practical implementation. The effectiveness of this control method is demonstrated by experiments using a boost converter.

基于非因果和非线性前馈控制的升压变换器输出电压精确跟踪控制

升压转换器是用于电动汽车和可再生能源应用的直流电源转换的关键部件。除对输出进行恒压控制外，为了实现负载的高效驱动，变压控制近年来备受关注。然而，升压变换器的动态特性表现为非线性和非最小相位特性。因此，前馈控制的逆模型是不稳定的，给高精度的电压轨迹跟踪控制带来了挑战。本研究旨在提出一种非因果非线性前馈控制器，以补偿升压变换器的非线性和非最小相位特性，并实现对输出电压轨迹的完美跟踪控制。本研究还建立了一种辨识电路参数和推导非因果控制输入时间长度的方法，以供实际实施。通过升压变换器的实验验证了该控制方法的有效性。
