摘要
目前温室大棚和植物生长柜的温度受外界环境影响波动比较大,常规的控制方法难以很好地控制环境温度。本文结合温度控制特性,针对常规PID控制自适应控制能力不强、控制效果欠佳等现象,提出一种模糊PID控制,并使用MATLAB进行验证。仿真结果表明:该控制策略具有良好的鲁棒性和稳定性,控制精度更高。
Currently the greenhouse, plant growth cabinet＇s temperature fluctuations in the external environment is relatively large, so it is really difficult for the conventional control method to well control the ambient temperature. Combining with some characteristics of the temperature control, as to the problems such as poor adaptive control capability for conventional PID, and the ineffective control, a fuzzy PID control is proposed, and it is verified by using MATLAB. Simulation results show that the control strategy has good robustness and stability, control more accurate.
