A dither control system for a laser gyro having a dither motor for dithering the laser gyro through a desired angular displacement, known as the command angle, in response to a drive signal. In order to help avoid saturation of the laser gyro, the dither control system reduces the command angle by command angle reduction data when the average drive signal applied to the dither motor exceeds a maximum drive value until the command angle reduction data reaches zero. The command angle reduction value is calculated by integrating the difference between the average drive signal and the maximum drive value.
