Abstract
In a research field on rendering of thermal sensation, Peltier device that can both heat and cool is often employed. Then recently, as the means to enhance the bandwidth of the thermal rendering, novel structure that utilizes temperature gradient prepared on metallic plate has been proposed. However, the performance of thermal control using the system is discussed little so far. In this study, analyses on tracking performance of temperature control are conducted using describing function. By using the describing function, it becomes possible to derive the frequency characteristics of saturation element included in the control system. Based on the analyses, relation between the tracking performance and the maximum/minimum temperatures at the ends of plate is discussed. The analyses are checked by numerical results.
