7.3 Transfer Function

The following command will return the transfer function of a system

7.3.1 TransferFunction[ System1]

Aliases: none
Description: TransferFunction[System1] returns the transfer function associated with the state space representation of System1.
Arguments: System1
Comments / Limitations: More complete documentation can be found in the Control Systems Professional manual. Changes to the CSP II package, since the CSP I require that inside NCControl.m we set the option
ReductionMethod NCInverse

for TransferFunction. For systems with commutative entries one still gets a correct answer from TransferFunction even with this option set. However, it may look different from that produced by CSP. Thus for a commutative [A,B,C,D] system, one may want use the option
ReductionMethod DeterminantExpansion

which gives the same answer as the CSP default.
