Extremsum Seeking Control of a Photovoltaic Reverse Osmosis Desalination System under Uniform Irradiance Conditions

This research explores the sustainable solution to the escalating global water crisis by examining the inventive Employment of green power sources for the treatment of brackish water. Given the frequent criticism of conventional desalination processes for their environmental impact and energy consumption, the incorporation of alternative energy sources, including solar, provides an auspicious resolution to these issues. This article explores the motivation behind implementing Extremum Seeking Control (ESC) in photovoltaic reverse osmosis desalination systems to maximize efficiency and sustain ability. By dynamically adjusting system parameters in real-time based on feedback signals, ESC aims to find the operating point that maximizes energy efficiency and water production rate. Meanwhile, Lyapunov is used to regulate the DC bus. This work comprehensively articulates the control methodology and comprehensive modeling of the entire system. MATLAB/Simulink performs the design and regulation of the entire system.
