Experimental Study on Uniform Heating Control based on Temperature Difference Model

Thermal distribution in thermal processes, which is observed in both steady and transient states, causes inferior quality. Thus, uniform temperature control is extremely required in many industrial application fields for quality improvement. Conventional control based on black-box model is cheap for the control of thermal plant with strong interference. Therefore, we have proposed a novel control design method for uniform heating using the temperature difference model (TDM). In this paper the effectiveness of the proposed controller is evaluated experimentally.
