<xs:annotation><xs:documentation>
The trigger element provides a way to specify a property that controls
how the integrator works, and is designed for wind-up protection. If
the value of the property supplied to the trigger element is 0, there
is no effect. If the value of the trigger property is non-zero,
(positive or negative) then the integrator does not integrate and
holds the last value. If the trigger property value is negative, the
integrator value is reset to 0.0.

<xs:element name="pvdot" type="xs:string" minOccurs="0">
<xs:annotation>
<xs:documentation>
pvdot is the process variable time derivative. If not specified,
the derivative control action will be determined from the change
in the input from the last time step (divided by the time step
size). If pvdot is specified, the specified value will be used
instead. The difference may be minimal in practice - UNLESS there
is an unnatural step change in the input value. For instance, if
the control input (process variable) is alpha, an alphadot value
is calculated as mentioned from the previous value. If pvdot is
explicitly specified as alphadot (alphadot is calculated and is
available as a native property in JSBSim) the results can be
smoother - particularly if there is a step change in the error
signal (the input) due to a step change in the target state. To
be clear, pvdot is meant to be the time derivative of the
input parameter. If the input to the PID controller is pitch rate
then pvdot should be pitch acceleration. If altitude is the input
then pvdot should be altitude rate.
