The invention relates to a method and a device for increasing the linearity of a servo system, for instance a gun servo. The servo system comprises an oscillator (6) having a fixed frequency for superimposing a so-called dither signal on the control signal of the servo system. The frequency of the dither signal is so chosen below, about or just above the upper frequency limit of the servo system. The linear effect produced by the dither signal results in a higher gain attained in the system even for very small signals.
