Regulating loop for a digital regulator of an excitation rotating electric machine is suitable for operation as a generator delivering an output voltage tailored by an excitation current. The digital regulator comprises means of control of the excitation current and the regulating loop comprises, at input, a means of measurement by sampling the output voltage generating a measurement signal (Um), means of error calculation generating an error signal (e) equal to a difference between the measurement signal (Um) and a setpoint (U0), means of processing of the error signal (e) generating a regulating signal (Ysat) comprising in parallel a first amplifier, an integrator and an anti-saturation system, and comprising, at output, means of generation of a control signal (PWM) controlling the means of control as a function of the regulating signal (Ysat). In accordance with the invention, the anti-saturation system is a conditional detection system. |
