Information

Description

Real derivative controller with Automatic, Tracking mode and bias signal.
The control law is defined as

              sTd
  CS(s) = ------------ (SP(s) - PV(S))
           1 + sTd/N

Scheme

Name	Description	Conditional?
SP	Set Point	NO
PV	Process Variable	NO
CS	Control Signal	NO
TR	Track Reference signal	YES (useTS)
TS	Track Switch signal	YES (useTS)
Bias	Biasing signal	YES (useBIAS)
ATreq	AutoTuning request	YES (*)

The controller can have various operating conditions:

Automatic,
and Tracking

In the Automatic mode, the control output is computed with the integral control law, while in the tracking mode
it is defined by the input TR.

To note that in the tracking mode the output signal CS is equal to TR.
