Abstract

The greenhouse is a complex, non-linear and high order system, it combines two fields “hydraulic and thermal”, and then it is not easy to analyze and control it. Hence, simplification is used in order to obtain model which facilitate the global analysis. In this paper we present a linear and simplifed bond graph model of a greenhouse from the model developed by Abbes [1]. The MORA method is used for simplification, generally used for the reduction of monoenergetic system, in this paper we enlarged this method for the reduction of the multienergetic system. This linear model will be used later to analysis and control a greenhouse system.
