Catalog Description:

In this course, we examine the latest methods in modeling and simulation of complex engineered systems. We use a unified energy-based approach to systematically model systems that are comprised of constrained electrical, mechanical, thermal, and fluid components. Simulation is based on numerical solution of nonlinear differential algebraic equations (DAEs). Systematic modeling is based on DAE forms of Hamilton's and Lagrange's equation. Such DAE forms readily accommodate dissipation, nonholonomic equality constraints, time-varying parameters, nonlinearities, and excess coordinates. We also incorporate such topics as reduced order modeling, finite element modeling and simulation, hybrid systems, and system of systems.
