modelPIDHysteresisTimer
Example model for PID controller with hysteresis and timer
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Example that demonstrates the use of the PID controller
with hysteresis and off timer.
The example is identical to
Annex60.Controls.Continuous.Examples.PIDHysteresis,
except that the controller also has an off timer.
This timer keeps the control signal at y=0
for a period of minOffTime=1000 seconds.
This may be used to avoid short-cycling if the load is small
and the system has little heat capacity.
The figure below shows the control error
con.feeBac.y and the control signal
con.y.
