# piddata

Access coefficients of parallel-form PID controller

## Syntax

## Description

## Input Arguments

## Output Arguments

## Tips

If

`sys`

is not a`pid`

controller object,`piddata`

returns the PID gains`Kp`

,`Ki`

,`Kd`

and the filter time constant`Tf`

of a parallel-form controller equivalent to`sys`

.For discrete-time

`sys`

,`piddata`

returns the parameters of an equivalent parallel-form controller. This controller has discrete integrator formulas`IFormula`

and`DFormula`

set to`ForwardEuler`

. See the`pid`

reference page for more information about discrete integrator formulas.
