Model Reduction: Motivation

• Silicon Growth Simulation (gas flow velocity vectors shown)
  • Coupled, nonlinear PDEs governing transport of fluid momentum, heat energy, and chemical species in a multi-component gas mixture
  • 35,100 grid points
  • Computation time: minutes to hours

• Competing Objectives
  • Reduce complexity (number of state variables, system order, dimension)
  • Retain predictive capability

• Low Complexity
  • Reduced computational burdens
  • Simplified controller synthesis
  • More reliable implementations
