Patent ID: 7109674

Claim:
A method for regulating the average electromagnetic torque of a polyphase rotating electrical machine equipped with stator and/or rotor windings, which are supplied with a polyphase voltage and a polyphase current that are generated by an inverter, the inverter being formed by switches whose switching is controllable, this method including: a control step of switching the switches as a function of an instantaneous torque set point, using an exact response control process to do this so that the instantaneous torque set point is reached as soon as the next regulation time, and a step at each regulation time of calculating, from an average torque set point, the instantaneous torque set point to be applied so that the average of the instantaneous electromagnetic torque of the machine converges toward said average torque set point, which method includes a step of determining the value of the harmonics of the voltage and/or the current which are generated by the inverter, and wherein the instantaneous torque set point is also established during the calculation step as a function of this value of the harmonics, so as to produce an instantaneous torque set point suitable for limiting the difference between the average of the instantaneous electromagnetic torque, between two successive regulation times, and said average torque set point.
