Design of Uniform Temperature Controller based on Temperature Difference Model

Abstract Thermal distribution in manufacturing 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. To deal with these problems, we have proposed the temperature difference model (TDM) for thermal process. In this paper, the design method of uniform temperature controller for two-dimensional heat plate is proposed. And the effectiveness of the proposed system is clarified by experiments.
