The Texas Instruments Model 545 programmable logic controller is used to control the air pressure in a heating/ventilation simulator designed and built for a classroom experiment station. Through the use of the PLC's built-in PID algorithm, the pressure in the duct was controlled to within a 2% tolerance and over 72% of the sensor range for a load setting of 10%. The theory of PID controllers and their application to this problem are discussed. Also, the configuration of the simulator, and plans for future work are described.
