Partial interface for a digital controller

Information

  

Description

Partial interface for a digital controller, implemented through an algorithm.
The model has the following ports
NameDescriptionConditional?
SPSet PointNO
PVProcess VariableNO
CSControl SignalNO
satHICS at HIGH saturationNO
satLOWCS at LOW saturationNO
TRTrack Reference signalYES (useTS)
TSTrack Switch signalYES (useTS)
BiasBiasing signalYES (useBIAS)
MANManual Switch signalYES (useMAN)
CSincControl Signal incrementYES (useMAN)
FincForbid incrementYES (useForbid)
FdecForbid decrementYES (useForbid)


And some of them can be conditionally selected, by specifying a boolean flag.

AntiWindUp mode

If the boolean flag AntiWindup is tue the output of the block ( CS ) saturates at the values specified by CSmin and CSmax.

Tracking mode

If the boolean flag useTS is true, the inputs TS and TR are enabled.
When enabled, if the TS signal is true the output CS is forced to follow the track reference signal TR.

Manual mode

If the boolean flag useMAN is true, the inputs MAN and CSinc are enabled.
When enabled, if the MAN signal is true the output CS can be manually controlled via the signals CSinc and CSdec, that respectively increment or decrement the control signal.

Forbid mode

If the boolean flag useForbid is true, the inputs Finc and Fdec are enabled.
When enabled, if the Finc signal is true the output CS cannot grow up, while if Fdec is true it cannot decrease.

Discretisation

The controller is implemented directly through an algorithm, that represents the discretised version of the continuous time controller.
