Abstract:
A dither control system for a dithered ring laser gyro having a pickoff source for providing pickoff data representative of a measured dither angle and a command angle source for providing command angle data representative of a desired command angle, comprising:modulated data generating means for generating modulated data as a function of dither error data and noise; average drive data generating means for generating average drive data as a function of the dither error data; dither drive data generating means for generating dither drive data as a function of the modulated data; a maximum drive source for generating maximum drive data as a function of a maximum desired value of the average drive data; command angle reduction data generating means for generating command angle reduction data as a function of the average drive and the maximum drive data; and dither error generating means for generating the dither error data as a function of the pickoff data, the command angle data, and the command angle reduction data.
