SystemsModelDelayApproximate
SystemsModelDelayApproximate[sys, ord]
gives a delay-free system by using approximations of order ord of the time delays in system sys.
Details and OptionsDetails and Options
- The system can be either a StateSpaceModel or a TransferFunctionModel.
- For continuous-time systems, delays are approximated using PadeApproximant with order ord.
- For discrete-time systems, delays are approximated poles for the integer part of the delay and a Thiran all-pass filter of order ord for the fractional part of the delay.
