Abstract
The invention is a method of determining the position and the speed of the rotor in a synchronous electric machine using a state observer of the currents of the electric machine and the injection of signals. Thus, the invention provides position information which is accurate, notably at low speed, without using a position detector. The invention also is a control method and system for controlling a synchronous electric machine which accounts for the position determined for the rotor.
