Abstract

The external validation of a continuous system model is a process which involves comparison of the behaviour of a mathematical model with that of areal system which it is intended to represent. Although most methods of external validation involve comparisons of chosen output variables of the system and the model, an alternative is to compare the inputs needed to achieve a specified output time history. The paper provides an outline of established techniques for the development of inverse models and describes the application of one approach to the external validation of a nonlinear dynamic model of a laboratory-scale system involving two inter-connected tanks of water. It is shown that inverse simulation can provide a potentially useful tool for external validation of nonlinear dynamic models, especially when used in conjunction with other validation techniques.
