Abstract
The object of the invention is a method of controlling a permanent-magnet synchronous or synchro-reluctant three-phase rotary machine (), comprising the following steps: measuring a current (i, i, i) flowing through each phase of a stator of rotary machine (); first calculating, by use of a single proportional-integral controller, a switching control signal for controlling an inverter (), according to each measured current (i, i, i), and of a target value (T) of a mechanical torque provided by the rotary machine () or of a target value of an angular speed of a rotor of rotary machine () in relation to the stator wherein the inverter () is configured to convey electrical energy between a continuous electrical energy source () and each phase of the stator of rotary machine (); andcontrolling the inverter () by use of the calculated switching control signal.
