A key factor in parameter estimation is the selection of model structure within which the fit to observed data is to be achieved. For linear systems, bond graphs have proven to give excellent support in this respect. However, for systems undergoing abrupt transitions between different (linear) modes of behaviour, the situation is far more complex. To handle this, we exploit the features of the ideal switching element as introduced by Strömberg, Top and Söderman. This solves the question of physical modelling as well as how to derive the supporting information. The approach is demonstrated on a non-trivial example using a multiple Kalman filter estimator.
