This paper discusses about the modelling, control and regulation of solar water pumping network. A novel method of water level regulation is provided based on a Fuzzy logic controller. The main objective of this paper is to supply the water according to the needs of the users regardless of dynamic variations in the climatic conditions. The paper focuses on the design and optimization of the power generated from the Photo Voltaic Generator and to regulate the water in the tank. A fuzzy logic controller and algorithm controller are used to control the solar water pumping system. The controller generates the reference speeds necessary for the PWM generator to control each DC/DC boost converter considering water levels in three tanks and instantaneous value of the solar radiation. The performance of the controller is tested on a real time solar water pumping system in vizianagaram district. The system performance is tested under multi-operating conditions such as variable load and weather data using MATLAB/ SIMULINK environment. A comparison analysis is presented between algorithm controller and Fuzzy logic controller.
