Assessment of subspace fault detection algorithms on a realistic simulator-based example

We present in this paper a simulation-based assessment of our recently-presented subspace-based monitoring and diagnostics algorithms [2]. The study is based on a simple but realistic simulation of a rocket during flight with known dynamics. The faults are represented by changes in the mass matrix, and stationary as well as non-stationary excitations are considered. A new idea for a symmetrical use of the test is introduced that could have applications in FE-model updating.
