Abstract
The control system for a fiber-optic gyroscope comprises a phase modulator for modulating a phase of a light signal and a control unit for producing a control signal, by the magnitude of which the phase is modulated and which is fed to the phase modulator. Moreover, the control system comprises an integration unit for determining an integral value of an integral over an input signal. Here, the control signal assumes a first value or a second value depending on the integral value.
