Optimization and Sliding Mode Control Applied to a Solar Water-Pumping System
Authors: , ,
Abstract: Renewable energy (RE) is increasingly recognized as a viable and planned approach to achieving sustainable development. It effectively addresses climate change while also meeting energy needs. For rural communities that lack access to the electricity grid, using a solar energy system for water pumping presents an economically feasible solution. Our objective is to create a comprehensive model of the solar pumping system, suggest different control strategies, and evaluate how well each one performs in terms of improving system efficiency and energy quality. The pumping system incorporates a photovoltaic generator and power conversion units, which are directly connected to an induction motor that drives a centrifugal pump. The standard method for Maximum Point Positioning (MPPT) controllers is Perturb and Observation (P&O). However, this method often suffers from oscillation problems around the operating point. As a result, improving the performance of this algorithm has become a key objective for scientists. In this study, we have designed the P&O controller and compared its results with those obtained with the sliding mode control (SMC).
The simulation results showed that the SMC controller outperformed the P&O controller in terms of time to stabilize, loss of power, and oscillation at the operating point under different conditions.
