Abstract

The control loop of a digital controller for an exciter rotating electric machine is suitable for operation as a generator which delivers an output voltage regulated by the exciter current. The digital regulator comprises means for controlling the field current and a regulation loop comprising: at the input, measurement means for generating a measurement signal (Um) by sampling the output voltage; error calculation means (13) , which generates an error signal (e) equal to the difference between the measurement signal (Um) and the set point (U0); means (14, 15, 16, 17, 18, 20) for processing the error signal (e) , which generates a regulation signal (Ysat) and comprises a first amplifier (14), an integrator (15) and an anti-saturation system (23) connected in parallel; A means (38) of the control signal (PWM) of the control means. According to the invention, said anti-saturation system (23) is a condition detection system (24).

Description

technical field [0001] The invention relates to a proportional-integral regulation loop of a digital regulator device for an exciter rotating electrical machine of a motor vehicle. Background technique [0002] In a known manner, an exciter rotating electrical machine (unlike an electrical machine with permanent magnets) can generate motor torque or supply electrical energy only when an exciter current passes through its inductor. [0003] A field rotating electric machine of the common type very commonly used in the motor vehicle industry for alternator and starter functions, comprising a rotating inductor and a stator with multiple windings. [0004] When the electric machine is used as an alternator, the current generated by the rotating inductor in the windings of the stator is rectified to supply DC current to the vehicle's battery. [0005] The voltage depends on the rotational speed of the inductor, the connected load and the field current. [0006] For motor vehicl...
