摘要

自由活塞能量转换器是未来混合动力汽车以及固定发电应用的潜在技术。在自由活塞能量转换器中,活塞没有连接到曲轴上。相反,活塞运动是“自由的”,由线性液压或电动机器控制。与传统发动机相比,这种设计的主要优点是发动机布局更简单,转换效率大大提高。本文将自由活塞变换器建模为混合自动机。在此基础上设计了层次混合控制器。通过仿真研究验证了所提控制器的性能。

Hybrid modelling and control of a free-piston energy converter
Free piston energy converters are a potential technology for future hybrid vehicles, as well as stationary power generation applications. In a free piston energy converter, the piston is not connected to a crank-shaft. Instead, the piston movement is "free" and controlled by a linear hydraulic or electric machine. The major advantages of such a design over the conventional ones are the simpler engine layout and much improved conversion efficiency. In this paper, the free piston converter is modeled as a hybrid automaton. Then a hierarchical hybrid controller is designed based on the model. The proposed controller performance is demonstrated by a simulation study.
