SystemsModelFeedbackConnect
SystemsModelFeedbackConnect[sys]
connects the outputs from sys to the inputs with negative feedback.
SystemsModelFeedbackConnect[sys, {con1, ...}]
only feedback connect the outputs and inputs in 
.
SystemsModelFeedbackConnect[sys1, sys2]
connects the outputs of 
to 
and the outputs of 
to the inputs of 
in feedback.
SystemsModelFeedbackConnect[sys1, sys2, {out1, ...}, {{in1, ftype1}, ...}]
connects output 
of 
to the i
input of 
and the j
output of 
to input 
of 
with feedback type 
.
Details
- The systems model
can be a StateSpaceModel or a TransferFunctionModel. - Connections
can be given as: -
{out,in} connect output out to input in in negative feedback {out,in,ftype} use positive or negative feedback type ftype - By default,
is a unity gain system. -
- The arguments in, out,
, and 
are integers specifying the positions of the input or output channels. - The ftype can be specified as
or 
for negative feedback, and 
or 
for positive feedback. The default type is 
.

Basic Examples (6)
A transfer function with negative unity feedback:
| In[3]:= |
| Out[3]= |  |
Connect two continuous-time systems in negative feedback:
| In[1]:= |
| Out[1]= |  |
Connect two discrete-time systems in negative feedback:
| In[1]:= |
| Out[1]= |  |
A state-space system with negative feedback:
| In[1]:= |
| Out[1]= |  |
Connect two state-space systems:
| In[1]:= |
| Out[1]= |  |
Feedback the second output to the first input:
| In[1]:= |
| Out[1]= |  |
