【摘要】：随着现代控制技术在农业领域的快速发展,温室环境控制系统的研究得到国内外学者的广泛关注。因温室环境的大滞后、非线性、多输入多输出(MIMO)等情况,难于构建精确数学模型结构,运用简单的基于模型的控制策略难以对其实施准确的调控。因此,如何将传统控制方法与现代控制方法结合实现温室环境的优化控制是目前温室控制系统亟待解决的实际问题。文中分别从PID控制、现代控制、智能控制和解耦控制等方面综述温室环境控制方法的研究现状,指出各种方法在温室环境控制中仍需解决的问题;认为可靠的温室系统模型是实现温室自动化控制的前提条件,提出将温室机理过程与系统辨识方法融合建立温室环境模型的新思路。
[Abstract]:With the rapid development of modern control technology in the field of agriculture, the research of greenhouse environmental control system has been widely concerned by scholars at home and abroad. Due to the large lag, nonlinear and multi-input and multi-output MIMOs in greenhouse environment, it is difficult to construct accurate mathematical model structure, and it is difficult to implement accurate control by using simple model-based control strategy. Therefore, how to combine the traditional control method with the modern control method to realize the optimal control of greenhouse environment is a practical problem to be solved urgently in the greenhouse control system. This paper summarizes the research status of greenhouse environmental control methods from the aspects of PID control, modern control, intelligent control and decoupling control, and points out the problems that need to be solved in greenhouse environmental control. It is considered that a reliable greenhouse system model is a prerequisite for the automatic control of greenhouse, and a new idea of establishing greenhouse environment model by combining greenhouse mechanism process with system identification method is put forward.
