SystemsModelSeriesConnect
SystemsModelSeriesConnect[sys1,sys2]
connects systems models sys1 and sys2 in series.
SystemsModelSeriesConnect[sys1,sys2,{{out11,in21},…}]
connects outputs out1i of sys1 to inputs in2i of sys2.
Details
- The systems model sysi can be a TransferFunctionModel, StateSpaceModel, AffineStateSpaceModel, or NonlinearStateSpaceModel.
- The inputs and outputs of the system produced by SystemsModelSeriesConnect are the inputs of sys1 and the outputs of sys2, respectively.
- The arguments in1i and out1i are integers specifying the positions of the input or output channels.
