COMPARISON OF PID CONTROLLER TUNING TECHNIQUES FOR TEMPERATURE PROCESS

Temperature measurement in today's industrial environments encompasses a wide variety of needs and applications. This paper gives an approach of tuning various controllers in a temperature process. The analysis has been done for tuning methods such as Closed ZN (Zeigler-Nicholas), Modified ZN with and without overshoots, IMC (Internal Model Control). A comparison between the performance criteria and between the time domain specifications has been carried out. The experimental results are compared and the method with better performance has been identified.
