This tnesis studies the control of a dual motor aigh speed motion picture camera. This camera is a modification of the one motor cameras presently in use today- First the system model is developed and then the control system is examined for the ideal tachometer. Next, non-ideal characteristics of tne tachometer signal as derived from an optical tachometer are discussed. Included in this section is the need to have pretensioning prior to the filming and deceleration at the end of the filming. The remainder of the thesis examines phase locked loop techniques for speed control of the high speed camera
