Abstract
The rotary electrical machine is capable of functioning as a generator and outputs a continuous output voltage (Ub+) that is adjustable by an excitation current. The digital regulator () of the machine comprises an excitation current control means () and a control loop () that includes a device () for measurement, by sampling, of the output voltage (Ub+), the measurement device generating a signal sampled at a predetermined first sampling frequency (F). The machine has a bandwidth that is limited by a predetermined first cutoff frequency (F). The measurement device includes an apparatus for oversampling such that the first sampling frequency (F) is greater than twice the first cutoff frequency (F), and the control loop also includes an apparatus () for decimating the sampled signal.
