基于模糊PID的智能温室控制系统设计与仿真

摘要

针对目前温室控制系统运行中存在的问题,开发了一种基于上、下位机结合和模糊PID控制算法的新型智能温室无线监控系统.本系统通过数据的无线接收与发送实现自动监测温室内各个测量节点的植物生长因子,根据模糊PID控制算法驱动执行单元实现远程控制.利用MATLAB工具对控制过程进行仿真试验,结果显示控制过程平稳,可以满足控制要求.%Aiming at the problems existing in the running of greenhouse control system, A new type of intelligent greenhouse wireless monitoring system was developed based on the upper and lower computer, fuzzy PID control algorithm. This system automatically monitors plant growth factor of each measurement nodes in the greenhouse through the wireless sending and receiving data,and drives the execution unit according to the fuzzy PID control algorithm to realize the remove control. The simulation of using MATLAB to control the process was carried out. The simulation results showed that the control process is stable, this system could meet the control requirements.
