Steady state determination using bond graphs for systems with singular state matrix

Abstract: A bond graph procedure to get the steady state value for linear time-invariant sys-tems is presented. The general case of a singular state matrix is considered. The procedure is based on a junction structure configuration with derivative causality assignment, and on rela-tionships of the bond graphs with integral and derivative causality assignments. It is shown that the structurally null modes, i.e. the poles at the origin, are cancelled for steady state. The key to cancel the poles at the origin is that the adjugate matrix of sIn Ap multiplies B
