Description

Presently in the industry, temperature control and heat flow control are conducted for many thermal devices, including the Peltier device, which facilitates heat transfer on the basis of the Peltier effect. Generally, temperature control compensates for the heat flowing from the external environment, while the heat actively flows into the system during heat flow control. Thus, temperature control and heat flow control differ from each other. However, there have been no detailed discussions on a thermal control process in which the thermal conductance of control ranges between 0 and ∞. This paper focuses on the thermal conductance of control and the construction of a thermal conductance control system for a Peltier device using a heat disturbance observer. When using the thermal conductance controller, the thermal conductance of control is altered, and the system becomes thermally compliant with the external environment. This paper also shows the experimental results that confirm the validity of the proposed control system.
