The steady state of LTI systems modelled by bond graphs through equivalent systems

Two general junction structures of Bond Graphs in Integral (BGI) and Derivative (BGD) causality assignments are proposed. In order to determine equivalent systems, the relationships between BGI and BGD are established. By using these relationships the steady state in a bond graph approach can be obtained. The equivalent systems allow to consider singular state matrix of a system represented by a BGI. An example to get the equivalent system and steady state is analyzed.
