Abstract : A series of experiments is undertaken to prove or disprove an hypothesis stated in AFFDL-FDCC-TM-65-34 (AD-647 749). This hypothesis stated that in a control system in which the input and time varying pure gain controlled element combine to require a recognizably periodic stick output to null system error, the entire effect of the time varying gain is to produce an apparent modification of the system input. The time varying pure gain is periodic and the three frequencies chosen for this set of experiments are identical to three of the frequencies in TM-65-34. The results are briefly discussed, conclusions drawn and performance data are presented. (Author)
