- Description
- In this paper, we apply a continuous-time system identification method, known as the Simplified Refined Instrumental Variable method for Continuous-time systems (SRIVC), to estimate transfer function models of a flexible cantilever beam with measurements taken at two locations on the beam using a high-speed camera. The accuracy of the obtained models is validated against data records that are independent from the datasets used for estimation. The parameters of interest of the cantilever beam, including the natural frequencies and damping ratios of the vibration modes, are then extracted from the continuous-time transfer function coefficients. A discussion on the physical meanings of the transfer function zeros is also provided with respect to the locations of the measurements.
