You can upsample only when you convert a discrete-time system to a new faster

sample time that is an integer multiple of the sample time of the original system.

Upsampling when possible, Tustin with Prewarping otherwise

Upsample a discrete-time system when possible and use Tustin with Prewarping

otherwise. Also, specify the prewarp frequency in Prewarp frequency (rad/s).

You can upsample only when you convert a discrete-time system to a new faster

sample time that is an integer multiple of the sample time of the original system.

Dependencies

Selecting either:

• Tustin with Prewarping


• Upsampling when possible, Tustin with Prewarping otherwise

enables Prewarp frequency (rad/s) on page 16-122.

Command-Line Information

Parameter: RateConversionMethod

Type: character vector

Value: 'zoh' | 'tustin' | 'prewarp'| 'upsampling_zoh'| 'upsampling_tustin'|

'upsampling_prewarp'

Default: 'zoh'

Prewarp frequency (rad/s)

Prewarp frequency for Tustin method, specified in radians/second.

Settings

Default: 10

Positive scalar value, smaller than the Nyquist frequency before and after resampling. A

value of 0 corresponds to the standard Tustin method without frequency prewarping.
