摘　　要：现代温室要求根据不同作物的生长条件,利用各种设备对温室内的环境因子进行监控。但是,环境因子控制是一个典型的大惯量、大时滞控制,容易产生较大的控制误差和系统震荡。本文就如何运用PID调节控制,实现一种稳定性高、动作准确的温室环境监控系统进行了阐述。Modern greenhouse requires us to use all kinds of equipment to the greenhouse to monitor environmental factors according to crops under different growth conditions. However, environmental factors control is a typical large inertia, it＇s easy to produce time delay, prone to error and larger control system shocks. This article focus on how to make regulate use of PID control, to get a high stability, precise movements of greenhouse environmental monitoring system.
