A description is given of a computer program developed to process data obtained from servo-response analyzer tests on prime mover fuel controls into analytical transfer functions suitable for representing the transient behavior of the fuel control in a computer simulation of the engine-generator set. A brief description of the servo-response analyzer tests made during the shock tube testing of the Enterprise diesel engine-generator set at Aberdeen Proving Ground is given to outline the data acquisition method. The fuel control system tested consisted of a Woodward Governor Company type EG-A electronic sensing and control unit with a type EG-B35 electro-hydraulic actuator. The servo-response analyzer EMR Model 1410 applied sine waves at selected frequencies as input stimuli to the system and measured the sine wave responses at the output points of interest in the system. The measured output was then processed by computer to obtain the transfer function characterization in an analytical form.
