| 摘 要： | 由于DC/DC开关变换器具有许多优良的特性,近年来得到了许多应用。基于变结构控制的滑模控制方式可被应用于各种开关变换器的控制,电流模式控制方式只是特定地应用于DC/DC变换器的控制。然而,在大负载电流和输入电压波动的情况下,这些控制方式的补偿能力明显不足。文章综合这两种控制策略提出了一种新的控制策略和获得动态参考电流的方法,并进行了仿真分析。结果证明,这种动态参考电流的获得方法能够减轻大负载电流和输入电压波动的影响。

| Abstract: | Many recent applications utilize DC/DC Switching converters for their good specifications. The SM (Sliding Mode) control scheme based on VSS (Variable Structure System) theory has been used in all switch mode converter types, whilst CM (Current Mode) control scheme is particularly applied to DC/DC converters. Nevertheless, these control strategies have some inability to compensate large load current and input voltage variations. In this paper, a new control strategy by compromising both schemes and derivation of dynamic current reference is proposed, analyzed and simulated. Moreover, derivation of a new dynamic current reference is also carried out to mitigate the large load/input voltage variations effects. |
