Wind Energy Conversion System using Predictive Control with Lyapunov Based Observer

Storm Power translation system is a reliable renewable power translation scheme. The generated power of wind energy translation system tends to fluctuate due to the wind mill production power is generally relative to the cube of wind velocity that is not always constant. An advanced control strategy must be used to provide the wind power output as maximum and more reliable. A novel control strategy, nonlinear generalized predictive control law in support of rotating side converter of two fold victual Induction Alternator established storm turbine is designed. The control plan based on two loops: The inner Torque-Current control loop based on NGPC provides the rotor reference voltage toward the rotating side converter as well as the outer NGPC based velocity control loop supplies the suggestion electromagnetic torque to inner loop. To give amazing ability to handle system conflict and enhance robustness of the controller, an aerodynamic torque observer is designed which is considered as an unknown perturbation and integrated with NGPC controller. Finally, simulations are done using MATLAB/ Simulink. Simulation results show the projected control strategy that maximizes the necessity of the WECS power output during variations in wind speed.
