Fuzzy Logic Implementation for Power Efficiency and Reliable Irrigation System (PERIS) of Tomatoes Smart Farm

Abstract

This paper presents an intelligent motor speed controller for Three Phase Motor with Variable Frequency Driver (VFD) for irrigation system of Smart Farming using fuzzy logic algorithm developed inside a Micro-Control Unit (MCU) environment or MCU on Power Efficiency and Reliable Irrigation System (PERIS). The desired motor speed controller is obtained using fuzzy inputs that consider three phenomenon such as: availability of energy within the system, reservoir water level and environment temperature. These fuzzy inputs are feedback data from the water reservoir level sensor (plant water requirements), environment/temperature sensor and current sensor. Different frequencies were used to test the controller’s performance in real time undergoing different water level and power load variations. The whole system is powered by photovoltaic cells, it can quickly and accurately calculate water demand amounts of crops, which can provide a scientific basis for power-savings and water-savings for irrigation. Experiment results showed that the developed controller is efficient, reliable and robust.
