This Dissertation presents the development of a multi-axial sensor along with shape determination methods on multiple degrees of freedom of launch vehicles, relying on fiber optic strain sensors. The main advantage of this system with respect to traditional Inertial Measurement Units (IMU) is that it can resolve the entire shape of the vehicle and extract the amplitudes of each mode shape in real time, without relying on notch filters or other lag-inducing devices that may impact controller performance. Two shape determination methods are presented, one based purely on the assimilation of the sensor as an Euler-Bernoulli beam, whereas the second method is based on modal decomposition of the strain measurements.

520 $a This Dissertation presents the development of a multi-axial sensor along with shape determination methods on multiple degrees of freedom of launch vehicles, relying on fiber optic strain sensors. The main advantage of this system with respect to traditional Inertial Measurement Units (IMU) is that it can resolve the entire shape of the vehicle and extract the amplitudes of each mode shape in real time, without relying on notch filters or other lag-inducing devices that may impact controller performance.

520 $a Results from a scaled down, laboratory sensor acquiring data at a frequency of 1kHz, successfully extracts the shape of a dynamic system up to the third mode shape in bending, as well as extracting coupled structural modes including bending in two directions and torsion at the same time. Prospective applications of these methods and system are also discussed in this Dissertation. (Abstract shortened by ProQuest.).
