An automatic, electronic controller was designed for use with
adiabatic calorimeters. The controller employed reset action, and
its behavior at different system gains was analyzed using the
analytic techniques of feedback control theory. In accord with the
analysis satisfactory performance was obtained with a calorimeter
characterized by large thermal lags, but marginal performance was
obtained with another calorimeter characterized by a rapid thermal
response. A second controller, which employs reset and proportional
action gave satisfactory results during preliminary testing for both
calorimeters.
