Abstract
A regulating loop for a digital regulator of an excitation rotating electric machine for operation as a generator delivering an output voltage tailored by an excitation current. The digital regulator comprises a control device for controlling the excitation current and the regulating loop comprises, at input, a measuring device for measurement by sampling the output voltage generating a measurement signal (Um), an calculation device generating an error signal (e) equal to a difference between the measurement signal (Um) and a setpoint (U), a processing system for 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, a generation system for generation of a control signal (PWM) controlling the control device as a function of the regulating signal (Ysat). The anti-saturation system is a conditional detection system.
