Compute discrete-time derivative
Simulink / Discrete
The Discrete Derivative block computes an optionally scaled discrete time derivative as follows
where
and are the block input and output at the current time step, respectively.
is the block input at the previous time step.
is an optional scaling factor, specified using the Gain value parameter.
is the simulation's discrete step size, which must be fixed.
Note
Do not use this block in subsystems with a nonperiodic trigger (for example, nonperiodic function-call subsystems). This configuration produces inaccurate results.
