Integrated Motion Measurement for Flexible Structures using a Modal and Krylov Subspace Model Reduction Approach

摘要

Integrated navigation for vehicle guidance is a well-known application of integrated motion measurement systems. For this, the vehicle is modeled as a single rigid body with six degrees of freedom to be determined. Stability problems with these systems occur, but can be avoided by distributing sensors over the vehicle structure. However, in this case the rigid body assumption has to be replaced to take the distributed sensors and the flexibility of the structure into account. By means of a modal approach and Krylov subspaces, appropriate models for the example of a flexible beam have been developed and tested based on simulated data.
