scipy.signal._ltisys:StateSpaceContinuous.to_discrete

Parameters

dt : float

The discretization time step.

method : str, optional

Which method to use:

• gbt: generalized bilinear transformation

• bilinear: Tustin's approximation ("gbt" with alpha=0.5)

• euler: Euler (or forward differencing) method ("gbt" with alpha=0)

• backward_diff: Backwards differencing ("gbt" with alpha=1.0)

• zoh: zero-order hold (default)

• foh: first-order hold

• impulse: equivalent impulse response

alpha : float within [0, 1], optional

The generalized bilinear transformation weighting parameter, which should only be specified with method="gbt", and is ignored otherwise
