Function File: sys = d2d (sys, tsam)

Function File: sys = d2d (sys, tsam, method)

Function File: sys = d2d (sys, tsam, 'prewarp', w0)

Resample discrete-time LTI model to sampling time tsam.

Inputs

sys

Discrete-time LTI model.

tsam

Desired sampling time in seconds.

method

Optional conversion method. If not specified, default method "zoh" is taken.

’zoh’

Zero-order hold or matrix logarithm.

’tustin’, ’bilin’

Bilinear transformation or Tustin approximation.

’prewarp’

Bilinear transformation with pre-warping at frequency w0.

’matched’

Matched pole/zero method.

Outputs

sys

Resampled discrete-time LTI model with sampling time tsam.
