PID Based Temperature Controller

Abstract: In today’s scenario temperature controlling plays vital role in most process industries. In this paper we are proposing a controller which can be used to control the temperature of a tank that is automatically tuned. Here temperature controller for water tank by using Delta PID controller is presented. The mathematical model of same is developed. The model is tested by using MATLAB software. There are many kinds of controlling mechanisms, i.e. on- off type controller, proportional controller, digital sensing mechanism, PID controller etc. Among of them, PID controller is the best known controller within affordable range. The results from Mathematical model and PID controller are verified and the results obtained were much encouraging.

Keywords: PID controller, proportional controller, Delta PID & Temperature control.
