ABSTRACT: This paper focuses on the speed control of a mill driven by an Asynchronous Motor (AM) powered by a solar photovoltaic energy source. As solar energy gains importance in the energy transition, artisanal mills are showing promise in improving rural life. However, speed variations caused by solar irradiance can affect their efficiency. The study proposes a comprehensive modeling of the system and explores advanced control strategies and optimization methods to optimize the performance. Traditional control approaches based on Foc and scalar strategies are examined, and the optimization considers the control and design parameters of the photovoltaic system. The results obtained by simulations in Simulink confirmed the performance of the strategies with good speed control regardless of the variation of load and irradiation.
