Intelligent Controller for Temperature Process

The goal of any temperature controller design is to keep the temperature of the target device on the desired value defined by the user as accurately as possible and using as little energy as possible. . The very control of temperature can be achieved by causing heater power to be simply switched on and off according to an under or over temperature condition respectively. Ultimately, the heater power will be regulated to achieve a desired system temperature but refinement can be employed to enhance the control accuracy. The temperature process is highly nonlinear and design of robust controllers for such nonlinear systems is a challenge. This paper proposes a novel method for the control of temperature process. The traditional PI controllers which are in practice produce high overshoot and the design procedure seems complex. The proposed intelligent controller offers better performance in terms of overshoot and settling time and thus increases the robustness of the system. This paper describes the modeling of the temperature process in detail and discusses how the process responds to conventional and intelligent controllers.
