摘要
温度变化的惯性比较大,传统的非连续控制法的精度较低。设计了系统硬件,根据PID算法构建了蔬菜大棚温控数学模型,采用Vb编写了计算机用户控制界面。结果表明:PID控制方式能使被控对象在长时间范围内不出现太大的漂移变化,实现较为精确的控制。
The inertia of temperature change is larger, and the traditional non continuous control way＇s precision is low. The system hardware is designed, mathematical model for controlling temperature of vegetable greenhouse is constructed according to the PID algorithm., and a control interface to computer user is writed by using Vb. The results show that： PID control method can make the object controlled is not too much of a drift in long range,and achieve more precise control.
