A review of proper modeling techniques

T Ersal, HK Fathy, DG Rideout, LS Louca, JL Stein - 2008 - asmedigitalcollection.asme.org
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 …
