Feedback Control in a Stirred-Tank Reactor

This Demonstration shows a simple feedback control for a stirred-tank reactor.

Details

Nomenclature:

T

r

: reactor temperature (°C)

T

sens

: temperature measured by a sensor (°C)

T

0

: temperature of inlet water (°C)

T

set

: setpoint temperature (°C)

Q

c

: proportional-integral feedback controller model

You can create disturbances in the flow rate and inlet temperature or set the "proportional control constant" slider to 0 to disconnect the controller and observe the temperature response to these changes.
