Algorithm
The system used for the feedback loop, Sys2, is optional. If it is not
specified, a default state-space system is used with NULL matrices for A2,
B2, and C2 and an identity matrix for D2 so that unity gain feedback is
implemented.
From Figure 3-4 and the state-space definitions of the systems, you derive
the following equations:
x
·1=A1x1Be1
+
y1=C1x1D1e1
+
x
·2=A2x2B2y1
+
y2=C2x2D2y1
+
e1=u1y2
