In a significant advancement for the renewable energy sector, researchers have developed an innovative electromagnetic torque controller designed specifically for variable-speed wind energy systems. This new controller, which integrates sliding mode control, fractional calculus, and neural networks, promises to enhance the efficiency of wind turbines, potentially transforming the landscape of electricity production from wind.
Yattou El Fadili, the lead author from the Computer Science, Signal, Automation, and Cognitivism Laboratory at the Faculty of Sciences Dhar El Mahraz, Sidi Mohamed Ben Abdellah University in Morocco, emphasized the critical role of effective control systems in maximizing energy capture. “Our research aims to address the challenges faced by current wind energy systems, particularly the chattering phenomenon that can lead to instability and inefficiencies,” El Fadili explained.
The chattering phenomenon, characterized by high-frequency oscillations around the sliding surface, poses a significant problem for traditional sliding mode control methods. This instability can damage turbine components and reduce overall performance. The newly proposed controller mitigates these issues by utilizing fractional calculus to model dynamic behavior more accurately and employing neural networks to adapt to varying wind conditions.
The implications of this research extend beyond technical improvements; they could have substantial commercial impacts as well. By increasing the efficiency of wind turbines, this controller could lead to higher electricity production rates, making wind energy a more attractive and viable option for energy providers. As countries and companies strive to meet renewable energy targets, technologies that enhance the performance of wind systems will be in high demand.
El Fadili’s team conducted extensive emulation tests under varying wind speeds, demonstrating the controller’s effectiveness in real-world scenarios. “The integration of sliding mode control, fractional calculus, and neural networks allows us to create a robust and adaptive control system that learns and improves over time,” he noted, highlighting the controller’s potential for long-term operational benefits.
This research, published in e-Prime: Advances in Electrical Engineering, Electronics and Energy, underscores a pivotal moment in wind energy technology. By addressing key challenges and enhancing performance, it paves the way for future developments in renewable energy systems. As the energy sector continues to evolve, innovations like these will be crucial in driving the transition towards more sustainable energy sources.
