.BuildSysPro.IBPSA.Obsolete.Controls.Continuous.Examples.PIDHysteresisTimer

Information

Example that demonstrates the use of the PID controller with hysteresis and off timer. The example is identical to IBPSA.Obsolete.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.
