Simulink Control Design™ - MathWorks

conversion methods are set to Trapezoidal by default. To override this setting, use

setBlockRateConversion.

Input Arguments

st — Interface for tuning control systems modeled in Simulink

slTuner interface

Interface for tuning control systems modeled in Simulink, specified as an slTuner

interface.

blk — Block

character vector | string

Block in the list of tuned blocks for st, specified as a character vector or string. You can

specify the full block path or any portion of the block path that uniquely identifies the

block among the other tuned blocks of st.

Example: blk = 'scdcascade/C1', blk = "C1"

Output Arguments

method — Rate conversion method

'zoh' | 'foh' | 'tustin' | 'matched'

Rate conversion method associated with blk, returned as one of the following:

• 'zoh' — Zero-order hold on the inputs


• 'foh — Linear interpolation of inputs


• 'tustin' — Bilinear (Tustin) approximation


• 'matched' — Matched pole-zero method (for SISO blocks only)

pwf — Prewarp frequency for Tustin method

positive scalar

Prewarp frequency for the Tustin method, returned as a positive scalar.

If the rate conversion method associated with blk is zero-order hold or Tustin without

prewarp, then pwf is 0.
