ControlLogic System

The ControlLogic system is an extension of MOOSE's Controls system. Standard MOOSE Controls can be created within a [ControlLogic] block or a [Controls] block. THMControls, however, which have additional functionality, can only be created within a [ControlLogic] block.

While MOOSE Controls work "directly" with controllable parameters, THMControls can work with an additional layer, control data. A THMControl can:

  • Declare new control data

  • Retrieve control data declared elsewhere

  • Change control data values

  • Set controllable parameters in MOOSE objects using control data

The main advantage of this additional capability is to chain control operations together, which is useful for composing realistic control systems.

Objects and Associated Actions

Available Objects

  • Thermal Hydraulics App
  • CopyPostprocessorValueControlForwards the value of a postprocessor to a ControlData named with the name of the postprocessor.
  • DelayControlTime delay control
  • GetFunctionValueControlSets a ControlData named 'value' with the value of a function
  • PIDControlDeclares a control data named 'output' and uses Proportional Integral Derivative logic on the 'value' control data to set it.
  • ParsedFunctionControlControl that evaluates a parsed function
  • SetBoolValueControlControl object that reads a boolean value computed by the control logic system and sets it into a specified MOOSE object parameter(s)
  • SetComponentBoolValueControlControl to set a boolean value of a component parameter with control data boolean
  • SetComponentRealValueControlControl to set a floating point (Real) value of a component parameter with control data boolean
  • SetRealValueControlControl object that reads a Real value computed by the control logic system and sets it into a specified MOOSE object parameter(s)
  • SmootherControlComputes a moving average value of the input control with a user-specified number of points to average. The output control value is named 'name:value', where 'name' is the name of the control object.
  • THMSolvePostprocessorControlControl the solve based on a postprocessor value
  • TerminateControlTerminates the simulation when a THMControl boolean data becomes true
  • TimeFunctionComponentControlControls a parameter in a Component using a function
  • UnitTripControlTrips a boolean based on the evaluation of a parsed condition expression
