Continuous PID
Model of a parallel continuous PID controller.
Library
GFLIB
Description
Performs a continuous PID controller. For a parallel PID controller, the transfer function in s-domain takes form:
Parameters and dialog box
The PID pane of the Continuous PID block dialog box appears as follows:
5 types of PID controller are available (PID, PI, PD, P and I). Proportional, Integral and Derivative gain are user-defined as well as Filter coefficient.
The Limits pane of the Continuous PID block dialog box appears as follows:
At this pane it's possible to turn on the output saturation with desired limits. In addition there is an optional anti wind-up if the controller contains an integration part.
Inputs and outputs
Inputs:
err - input error signal
Outputs:
out - output control signal
Integ - output from integration part
LimitFlag - indicates saturation
