【摘要】：温室系统是一个复杂的系统,系统中各变量间具有强耦合关系,影响控制的精度和效率,也使得对温室系统精确控制的难度增加,所以在温湿度二维系统的基础上,增加对CO2浓度的考虑,建立温室系统的三维数学模型。通过研究前馈补偿算法在三维系统中的应用,对温室系统中的3个主要变量进行解耦,利用Matlab建立温室系统数学模型,然后进行仿真研究,通过与仿真结果对比,证实了前馈补偿算法应用于仿真系统的高效性和稳定性。
[Abstract]:Greenhouse system is a complex system, which has a strong coupling relationship among variables, which affects the precision and efficiency of control, and makes it more difficult to control the greenhouse system accurately, so it is based on the two-dimensional temperature and humidity system.The three-dimensional mathematical model of greenhouse system was established by increasing the consideration of CO2 concentration.By studying the application of feedforward compensation algorithm in 3D system, the three main variables in greenhouse system are decoupled, and the mathematical model of greenhouse system is established by using Matlab, and then the simulation research is carried out, and the results are compared with the simulation results.It is proved that the feedforward compensation algorithm is efficient and stable in the simulation system.
