Abstract : 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. (Author)
