Abstract
An electronic speed error signal processing circuit is provided which attenuates rapid fluctuations ocurring in the speed error signal used to control the fluid inlet valve of a fluid driven prime mover. Such fluctuations contribute greatly to valve wear by causing 'valve flutter,' the continual rapid opening and closing of the inlet valve as the speed control system of a prime mover instantaneously responds to any small speed error signal fluctuation. By attenuating these rapid fluctuations, valve flutter is reduced.
