A study of dual sensing in reactor controls

A problem of dual sensing is postulated wherein a reactor power level is monitored with two unlike sensing devices - a slow sensor, and a fast sensor that is subject to error due to drift. An error channel, designed to combine the outputs of the two sensors so as to eliminate the undesirable characteristics of each and yield a combined output more satisfactory than that realizable from either sensor operating alone, is studied both analytically and experimentally.
