On the real time estimation of the wind speed for wind energy conversion systems

This paper presents the experimental results of the real time estimation of the wind speed for a wind turbine. In order to estimate the wind speed, an adaptive observer is employed. A wind turbine emulator was designed for validating the theoretical results. The wind turbine emulator is able to simulate the dynamics of a real wind turbine. For emulation purposes the wind speed is considered as a known input. On the other hand, for the adaptive observer the wind speed is considered as an unknown parameter. A free Linux-based real time platform was used for the experimental setup.
