Description

This model is a combination of an I storage element and a C storage element. Consequently the constitutive equation must be written as a matrix-vector multiplication. The constitutive equation of this element is given below:

 

state1 = int(p1.f);

 state2 = int(p2.e);

 p1.e = state1*a11 + state2*a21;

 p2.f = state1*a21 + state2*a22;

 output2 = state1;

 output2 = state2;

 

The Maxwell reciprocity demands a12 = a21. Therefore only 3 matrix parameters are necessary.

Interface

Ports
