Eckhard received the diploma degree from Technische Universität, Berlin, Germany, 2005, in mechanical engineering. After graduating he was with independent engineering companies, dedicated to wind turbine prototype development, working as a design engineer, project manager and managing director for five years.
He is currently research fellow with the Department of Control Engineering, University of Applied Science, Berlin, Germany.
He studies control systems and control applications, especially wind energy. Some of his recent wind energy control projects include load mitigation on wind turbines employing observer based feedforward control.
His doctoral project is supervised by Prof. Martin Kühn, head of Wind Energy Systems research group at Carl von Ossietzky University, Oldenburg, Germany.
„Load Mitigation for Wind Turbines - Implemention of a Taka-gi-Sugeno wind speed observer in feedforward control ":
The objective of the doctoral project is the load mitigation for wind turbines employing a model based, wind depended feed forward control. For that purpose a Takagi-Sugeno (TS) observer is implemented to reconstruct the wind speed from the rotor blade tip displacement. Apart from a considerably simplified blade model a much more detailed, structural dynamic blade model is employed within the TS observer to improve the reconstruction performance.
The TS observer is assessed systematically with other conventional observer concepts regarding reconstruction performance, robustness and extreme as well as fatigue load mitigation.
