Abstract
A method is described for regulating the average electromagnetic torque of a polyphase rotating electrical machine, supplied with a polyphase voltage and a polyphase current that are generated by an inverter. The method comprises a step of controlling the machine, using an exact response control process to do this, a step of determining the value of the harmonics of the voltage and/or the current which are generated by the inverter, and a step of calculating the instantaneous torque set point as a function of the value of the harmonics and an average torque set point, 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.
