Bond Graph
Domains: Continuous. Size: 1-D. Kind: Block Diagrams, Bond Graphs.
This model represents a two port C-element. Normally the equation of a two port C-element is written in vector notation as:
p.e = (1/C) * int(p.f)
When the C matrix is singular simulation will not be possible. Therefore the element is described in a safer notation as:
p.e = A * int(p.f) , with A = (1/C);
Both ports have a preferred effort out causality:
state1 = int (p1.f);
state2 = int (p2.f);
p1.e = a11*state1 + a12*state2;
p2.e = a21*state1 + a22*state2;
