Abstract

In thermal processes, thermal distribution on the conduction surface is observed in both steady state and transient state. Uniform temperature control is required in many industrial application fields for quality improvement. For thermal plant with strong interference, decoupling controller using black-box model based on input-output relations has been applied. In this paper, a novel cell model with feedback structure which describes the thermal interaction explicitly is derived, and its application to a new decoupling control is proposed. First, uniform cell model is considered based on physical energy, and is applied to experimental plant. The thermal distribution is simulated by the FEM method. Secondly, design of decoupling controller using the proposed cell model is shown, and the effectiveness is evaluated.
