Paper Abstract

In this paper we discuss the use of a distributed-effect modal domain optical fiber sensor (MD sensor) as a component in an active control system to suppression vibrations in a flexible beam. We integrate the sensor model into the model for a flexible structure. Based on this system model, a control system with a dynamic compensator is designed to add damping to the low order modes of the flexible structure. To verify the modeling procedure a cantilevered beam was instrumental with a piezoelectric actuator and an MD sensor. It is shown that experimental responses closely match simulated responses for both open ioop and closed loop tests.
