Abstract

Fertigation control system is developed based on fuzzy logic controller that aims to perform high efficiency of water and fertiliser usage in fertigation process in agricultural field to ensure adequate moisture and nutrients are delivered to the crops. The main objective of the system is to accurately deliver the certain amounts of water and fertiliser to the chili plants. The parameter readings of agricultural including pH value and soil moisture level are measured as inputs. The outputs for the system is the water pump and the fertiliser pump. Fuzzy logic is implemented as the controller in this system to control the water and fertiliser amounts to soil in order to maintain the moisture level and pH value of soil. The fuzzy logic controller is built on MATLAB software and the fuzzy rules designed in MATLAB are programmed in the Arduino microcontroller to regulate the amount of water and fertiliser for the plant. Simulink model of the fertigation system control system is constructed to observe the output's performance. Flowchart is used to present the working principle of the control algorithm in this system. Real time implementation of this system is conducted on a chili plant where the growth of plant with Fuzzy logic controller has better growth in terms of the height of plant, the diameter of stems and the number of fruits compared to the chili plant with traditional method. In terms of water and fertiliser usages, the fertigation system with Fuzzy Logic uses less resources than the traditional method.
