Estimation of a nacelle dynamic motion of a wind turbine

A Kalman filter is applied to estimate the movement of a nacelle. The information of nacelle acceleration and strain gauge installed at the root location of tower is combined in Kalman filtering. A simple model of tower vibration is considered. A scale-down experimental rig simulating a tower and nacelle of wind turbine is constructed to test the performance of proposed estimator algorithm. The experimental results of using this rig are introduced.
