PROJECT TITLE :
Modal estimation by FBG for flexible structures attitude control
This work investigates an online mode form estimation methodology to estimate the time-varying modal properties and correct IMU readings in real time using distributed strain measurements of FBG sensor arrays. Compared to the notch filter approach, the proposed methodology removes structural vibration information while not adding section lag or transient dynamics. Numerical simulations on a versatile rocket attitude management and the experiments on a vertical test beam with configurable mass distribution are used for demonstration.
