Description
The Controlled Temperature Source block represents an ideal source of thermal energy that is powerful enough to maintain specified temperature difference across the source regardless of the heat flow consumed by the system.
Connections A and B are thermal conserving ports corresponding to the source inlet and outlet, respectively. Port S is a physical signal port, through which the control signal that drives the source is applied. You can use the entire variety of Simulink® signal sources to generate the desired heat flow variation profile. The temperature differential across the source is directly proportional to the signal at the control port S.
The block positive direction is from port A to port B. This means that the temperature differential is determined as TB – TA, where TB and TA are the temperatures at source ports.
Examples
House Heating System
Model a simple house heating system. The model contains a heater, thermostat, and a house structure with four parts: inside air, house walls, windows, and roof.

Programmatic Use: Add Block
To add the block programmatically, use the add_block function with one of these library block paths as the source.
"fl_lib/Thermal/Thermal Sources/Controlled Temperature Source"
Example: add_block("fl_lib/Thermal/Thermal Sources/Controlled Temperature Source","myModel/myBlock",MakeNameUnique="on")
For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
