Abstract

FBG sensors are an attractive solution for vibration control applications since they can provide a large number of measurements with a negligible effect on the mechanical properties of the controlled structure and without problems related to measurement layout and overall dimensions. The paper analyzes the limits on the use of swept laser FBG interrogators for control systems applications due to time delays. Results show that good control performance can be obtained at least up to 20 Hz.
