Abstract

The invention relates to a regulation system for an asynchroNOus motor by field oriented control, reacting to a torque set value (T) and a flux set value (.phi.). The flux set value is supplied from the torque set value by an operator carrying out first order low pass filtering (40) and calculating the square root (42) of the result of the filtering.
