【摘要】：溫室系統(tǒng)是一個復(fù)雜的系統(tǒng),系統(tǒng)中各變量間具有強耦合關(guān)系,影響控制的精度和效率,也使得對溫室系統(tǒng)精確控制的難度增加,所以在溫濕度二維系統(tǒng)的基礎(chǔ)上,增加對CO2濃度的考慮,建立溫室系統(tǒng)的三維數(shù)學(xué)模型。通過研究前饋補償算法在三維系統(tǒng)中的應(yīng)用,對溫室系統(tǒng)中的3個主要變量進(jìn)行解耦,利用Matlab建立溫室系統(tǒng)數(shù)學(xué)模型,然后進(jìn)行仿真研究,通過與仿真結(jié)果對比,證實了前饋補償算法應(yīng)用于仿真系統(tǒng)的高效性和穩(wěn)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.
