Active Heater Controller dialog box (Thermal/SST/ESC/Multiphysics)

Modeling Object
Name	Sets a name for the modeling object. Enter a meaningful name. You select this modeling object in the Thermal Loads dialog box.
Label	Sets a unique numeric identifier for the modeling object.
Description	Lets you enter a description for the modeling object.Click Description to enter a longer description.
Sensor
Temperature Sensor	Specifies how you define the temperature sensor.SelectedLocates the temperature sensor on the selected thermal elements. If the selection contains fluid elements, the software ignores them. To locate the temperature sensor on elements associated to selected geometry, use the Select Object option.To locate the temperature sensor on elements associated to the selected group, select the Group Reference check box.Non-Geometric ElementLocates the temperature sensor on a non-geometric element. Select an existing non-geometric element modeling object from the Non-Geometric Element list, or click Create Modeling Object to create a new non-geometric element.To search and filter objects, see Group Reference options.
Group Reference	Available when Temperature Sensor is set to Selected.Applies the temperature sensor to the selected group. For more information, see Group Reference options.
Select Object	Available when Temperature Sensor is set to Selected.Lets you select an object to locate the temperature sensor.Excluded lets you remove individual entities from your selected object.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Parameters
Type	Specifies the type of Active Heater Controller to create.ProportionalAdjusts the heat load based on a linear relationship between the load at the cut-in temperature and the load at the cut-off temperature that you specify in the Cut-in Temperature and Cut-off Temperature boxes.PID ControllerAdjusts the heat load according to the following relationship:Qinto the system=Qdefined[Kp**e(t)+Ki⌠e(t)dt+Kd**de(t)/dt+Offset]where:Kp is the proportional gain parameter that you define in the Gain box.Ki is the integral gain parameter that you define in the Integral Term Constant box.Kd is the derivative gain parameter that you define in the Derivative Term Constant box.e(t) is the error function over time computed as follows: e(t)=Ts—Telement(t), where Telement(t) is the temperature of a given element at time t and Ts is the target temperature that you define in the Set Point Temperature box.Offset is the bias parameter that you define in the Bias box.The total PID contribution, Kp**e(t)+Ki⌠e(t)dt+Kd**de(t)/dt+Offset, must be greater than or equal 1.	Qinto the system=Qdefined[Kp**e(t)+Ki⌠e(t)dt+Kd**de(t)/dt+Offset]				where:Kp is the proportional gain parameter that you define in the Gain box.Ki is the integral gain parameter that you define in the Integral Term Constant box.Kd is the derivative gain parameter that you define in the Derivative Term Constant box.e(t) is the error function over time computed as follows: e(t)=Ts—Telement(t), where Telement(t) is the temperature of a given element at time t and Ts is the target temperature that you define in the Set Point Temperature box.Offset is the bias parameter that you define in the Bias box.The total PID contribution, Kp**e(t)+Ki⌠e(t)dt+Kd**de(t)/dt+Offset, must be greater than or equal 1.
