Modelling of distributed parameter systems for control

A system model must represent the physical processes and enable reliable interpretations to be made, while not being too complicated computationally. The numerical solution procedure must be reliable and robust. The usual validation strategy for this point is to isolate subsets which are arranged to reflect the way in which the equations are derived. This does not directly indicate the number of solutions, but provides a basis for graphical representation of the equations which enables the common points to be identified. A parametric survey then generates response patterns from which general trends can be recognised, and this is important in validation
