DC-DC转换器本质上呈现混合行为，其由与连续动态相关联的一组离散模式描述。通过在离散模式之间切换来实现控制目标。本文提出了一种新的模型预测控制方法来优化DC-DC变换器的性能。该控制算法是针对DC-DC变换器的，充分利用了有限个模式的事实，将性能优化问题转化为一个组合优化任务。这种方法使得在线计算非常简单和有效的实现。
DC-DC converters by nature present hybrid behavior, which is described by a set of discrete modes associated with continuous dynamics. The control objective is accomplished by switching among the discrete modes. This paper presents a new model predictive control approach to optimize the performance of DC-DC converters. The proposed control algorithm is tailored to DC-DC converters, making full use of the fact of finite number of modes to transform the performance optimization problem into a combinatory optimization task. This approach has made the on-line computation very simple and effective for implementation.
