Positive finite value. Use to compute:



  • A discrete-time linear system from a continuous-time system.

  • A discrete-time linear system from another discrete-time system with a different
    sample time


0


Use to compute a continuous-time linear system from a discrete-time model.

Sample time rate conversion method


Method for converting the sample time of single-rate or multirate models.


This parameter is used only when the value of Linear system sample time on page 16-
256 is not auto.


Settings


Default: Zero-Order Hold


Zero-Order Hold


Zero-order hold, where the control inputs are assumed piecewise constant over the
sampling time Ts. For more information, see “Zero-Order Hold” (Control System
Toolbox).

This method usually performs better in the time domain.
