      Bond graph based modal representations and model reduction of lumped parameter systems 

      Louca, Loucas S. (Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Street, Nicosia 1678, CyprusCorrespondence Address: Louca, L.S.Department of Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Street, Nicosia 1678, Cyprusemail: lslouca@ucy.ac.cy, 2006)
      Modal analysis is extensively used to study dynamic behavior of continuous and lumped parameter linear systems. More specifically, modal analysis can be used for the analysis and controller design of dynamic systems. In ...

      Complexity of distributed parameter bond graph models 

      Louca, Loucas S. (The Society for Modeling and Simulation International, 2014)
      Modeling metrics and algorithms that assist the development of dynamic system models are essential for efficient use of modeling and simulation in everyday engineering tasks. Various modeling procedures have been proposed ...

      Extension and application of an algorithm for systematic identification of weak coupling and partitions in dynamic system models 

      Rideout, D. G.; Stein, J. L.; Louca, Loucas S. (2009)
      This paper reviews and extends a technique to detect weak coupling (one-way coupling or complete decoupling) among elements of a dynamic system model, and to partition and reduce models in which weak coupling is found. The ...

      Modal analysis reduction of multi-body systems with generic damping 

      Louca, Loucas S. (2014)
      Modal analysis of multi-body systems is broadly used to study the behavior and controller design of dynamic systems. In both cases, model reduction that does not degrade accuracy is necessary for the efficient use of these ...

      A model accuracy and validation algorithm 

      Sendur, P.; Stein, J. L.; Peng, H.; Louca, Loucas S. (American Society of Mechanical Engineers (ASME), 2002)
      Dynamic models of physical systems with physically meaningful states and parameters have become increasingly important, for design, control and even procurement decisions. The successful use of models in these contexts ...

      Power conserving bond graph based modal representations and model reduction of lumped parameter systems 

      Louca, Loucas S. (2014)
      Dynamic analysis is extensively used to study the behavior of continuous and lumped parameter linear systems. In addition to the physical space, analyses can also be performed in the modal space where very useful frequency ...

      A review of proper modeling techniques 

      Ersal, T.; Fathy, H. K.; Louca, Loucas S.; Rideout, D. G.; Stein, J. L. (Affiliation: University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United StatesAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, Nicosia, CyprusAffiliation: Memorial University of Newfoundland, Department of Engineering and Applied Science, St. John's, NL, CanadaCorrespondence Address: Ersal, T.University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2008)
      A dynamic system model is proper for a particular application if it achieves the accuracy required by the application with minimal complexity. Because model complexity often - but not always - correlates inversely with ...

      Systematic identification of decoupling in dynamic system models 

      Rideout, D. G.; Stein, J. L.; Louca, Loucas S. (2007)
      This paper proposes a technique to quantitatively and systematically search for decoupling among elements of a dynamic system model, and to partition models in which decoupling is found. The method can validate simplifying ...
