Parallel connection of two LTI models
parallel
sys = parallel(sys1,sys2)
sys = parallel(sys1,sys2,inp1,inp2,out1,out2)
parallel connects two LTI models in parallel. This function accepts any type of LTI 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 = parallel(sys1,sys2) forms the basic parallel connection shown below.
This command is equivalent to the direct addition
sys = sys1 + sys2
(See Addition and Subtraction for details on LTI system addition.)
sys = parallel(sys1,sys2,inp1,inp2,out1,out2) forms the more general parallel connection.
The index vectors inp1 and inp2 specify which inputs
of sys1 and
which inputs
of sys2 are
connected. Similarly, the index vectors out1 and out2 specify which outputs
of sys1 and
which outputs
of sys2 are
summed. The resulting model sys has
as inputs and
as outputs.
See Kalman Filtering for an example.
