: reactor temperature (°C)

: temperature measured by a sensor (°C)

: temperature of inlet water (°C)

: setpoint temperature (°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.
