In this article, a novel sampled-data control method is proposed for direct current to direct current converter. According to its switching property, the direct current to direct current converter is described as a switched affine system. A novel error tracking switching law is designed based on the multi-Lyapunov functions method and sampled-data control strategy with variant sampling intervals. The sufficient condition concerning the state of the constructed switched affine system converging to a finite region is developed, which guarantees the outcome voltage can approach the desired value and achieve the voltage adjustment. Based on it, the condition under uncertain parameters is developed as well, which would be more desirable in applications. The effectiveness of the proposed method is verified by numerical simulations. The proposed method is also applicable to other types of power converters.

在本文中，提出了一种新颖的直流到直流转换器的采样数据控制方法。根据其开关特性，将直流到直流转换器描述为开关仿射系统。基于多重李雅普诺夫函数法和具有可变采样间隔的采样数据控制策略，设计了一种新颖的误差跟踪切换律。提出了关于构造的仿射系统收敛到有限区域的状态的充分条件，这保证了输出电压可以接近期望值并实现电压调整。基于此，还开发了不确定参数下的条件，这在应用中将是更理想的。数值仿真验证了该方法的有效性。
