The Temperature Controller

The setpoint temperature for aluminium block was deter-mined using a temperature controller, which uses Servo loops. By obtaining the setpoint temperature using differ-ent types of Servo loops, we were able to determine which had the greatest control. For low setpoint temperatures, the PID controller showed greatest control but lost accuracy at higher temperatures. For overall control, the PI controller displayed the greatest control. We also determined that by taking all the data with the fan on, the block would display less dependance on the room temperature.
