Developing a Solar PV Battery-Powered Brushless DC (BLDC) Motor Water Pump System in MATLAB involves creating a simulation model that integrates solar photovoltaic (PV) panels, batteries, and a BLDC motor-driven water pump. The model enables analysis of various factors such as solar irradiance, battery charging and discharging, motor efficiency, and pump performance. By simulating the system in MATLAB, engineers can evaluate different control strategies and optimization techniques to maximize the pump's efficiency and water delivery under varying sunlight conditions and water demand. This approach facilitates the design and testing of sustainable water pumping systems for agricultural, irrigation, or remote applications, promoting energy efficiency and resource conservation.
