A note on POD model reduction methods for DAEs

Please always quote using this URN:urn:nbn:de:0296-matheon-3691
  • We review some known results for POD model reduction applied to ODEs. Then, these results are generalized to several types of DAEs. We provide algorithms for the model reduction and error bounds for the reduced order models. Some limits of the approach are pointed out and alternative methods for reduced order subspace approximation are presented. The POD approach is tested and evaluated for a medium sized DAE example from multibody dynamics.
