A new method of temperature control for the uniform heating

Uniform temperature control of heating plate, which has a wide thermal conduction area, is required in many industrial application fields. In this paper, a new method of uniform temperature control is proposed based on an idea of quasi-decoupling. The feature of the proposed method is easy to design a control system without the precise plant dynamics. The controller is designed using the gradient and average of temperature among the arbitrary points. The effectiveness of the proposed control method is confirmed by experiment.
