series
Series connection of two models
Syntax
series
sys = series(sys1,sys2)
sys = series(sys1,sys2,outputs1,inputs2)
Description
series
connects two model objects in series. This function accepts any type
of model. The two systems must be either both continuous or both discrete
with identical sample time. Static gains are neutral and can be specified
as regular matrices.
sys = series(sys1,sys2)
forms the basic series connection shown below.
This command is equivalent to the direct multiplication
sys = sys2 * sys1
sys = series(sys1,sys2,outputs1,inputs2)
forms the more general series connection.
The index vectors outputs1 and inputs2 indicate
which outputs y1 of sys1 and
which inputs u2 of sys2 should
be connected. The resulting model sys has u as
input and y as output.
Examples
Consider a state-space system sys1 with five
inputs and four outputs and another system sys2 with
two inputs and three outputs. Connect the two systems in series by
connecting outputs 2 and 4 of sys1 with inputs
1 and 2 of sys2.
outputs1 = [2 4]; inputs2 = [1 2]; sys = series(sys1,sys2,outputs1,inputs2)
