Infinite structure of the bond graph model is used to get the number of invariant zeros. In the linear time invariant case, null invariant zeros can be directly pointed out, it is no more true for linear time varying models. A new rule based on the finite structure of the bond graph model is given. Algebraic calculations of torsion modules clarify this difference. Based on a simple modified RLC circuit, different comparative approaches are proposed. A theoretical form based on Jacobson forms of system matrices is proposed and developed with a Maple programm. Some simulations with 20-sim illustrate the results.Show less >
