Abstract

The invention relates to the technical field of water and fertilizer irrigation control methods, and discloses a gray prediction fuzzy PID control method for water and fertilizer precision irrigation,which comprises the following steps: S1, combining a gray prediction control method, a fuzzy logic control method and a PID control method; s2, aiming at different irrigation modes and control objects, developing a serialized automatic irrigation control system; s3, adopting different irrigation modes for different plots and different crops through a serialized automatic irrigation control systemto realize precise control irrigation of water and fertilizer. The gray prediction fuzzy PID control method for water and fertilizer precision irrigation provided by the technical scheme of the invention can realize precision control of water and fertilizer irrigation.

Description

technical field [0001] The patent of the present invention relates to the technical field of water and fertilizer irrigation control methods, specifically, a gray prediction fuzzy PID control method and equipment for water and fertilizer precision irrigation. Background technique [0002] In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. And with the rapid development of science and technology, many places have begun to implement automated water and fertilizer irrigation in order to reduce manpower. [0003] In the process of automatic water and fertilizer irrigation, in order to realize automatic irrigation, it is generally necessary to control the power sourc...
