Models of power bond graph of micro-spraying system in sunlight greenhouse

微喷系统是日光温室中环境调节与控制、作物的生长与发育、优质和高产的根本保证。因此,微喷系统的性能对于日光温室的生产与效益有直接的影响。文中利用功率键图的理论与方法,分析、建立了温室微喷系统的键图模型,为研究日光温室微喷系统的动态性能、评价和改进微喷系统的设计奠定了理论基础。

A micro-spraying system holds a key to regulating and controlling environment in a sunlight greenhouse, promoting the growth and development of crops, and ensuring a better quality and higher yield of crops. As a result, the performance of a micro-spraying system exerts a direct effect on the production and benefit of a sunlight greenhouse. Power bond graph models of a micro-spraying system in a sunlight greenhouse are analyzed and built up by means of theory and method of power bond graph in the paper, which lays the foundations for studying the dynamic performance of a micro-spraying system in a sunlight greenhouse and appraising and improving the design of the system.
