Abstract

PURPOSE: To improve a stability of a system, by detecting a temperture at two points, and to minimize the change in a temperature of an object to be controlled corresponding to the change in an ambient temperature, by sufficiently increasing a loop gian.
CONSTITUTION: The signal T repersents a temperature of an object to be controlled, the signal Tc a temperature of a control stand surface of a thermoelectric element 2, the signal Ta an ambient temperature, the numerals 6 to 10 thermal resistances, the numerals 3 and 4 temperature detectors and the numeral 5 a difference amplifier. In the temperature control system composed in such a manner as noted above, the change in a temperature of the object to be controlled corresponding to the change in the ambient temperature is evaluated as a given-value-compressed value.
