Claim 1:
2. The control method according to claim 1, wherein:
the first step of detecting the angular position of the rotor of the electric machine is performed through the position sensors;
the second step of detecting the values of alternate current next to at least two phases of the input current to the electric machine is performed through at least two alternate current sensors, each the at least two alternate current sensors being electrically connected to a phase of a supplying circuit of the electric machine;
the third step of detecting the values of voltage and direct current supplied as input to the inverter is performed respectively through a direct voltage sensor and a direct current sensor, electrically connected to the supplying circuit of the inverter;
the fourth step of estimating the estimated torque supplied by the electric machine is performed by processing data detected by the position sensors, and the values of the alternate current in the first step and in the second step, and data obtained by means of simulations of the electric machine;
the fifth step of computing the check torque supplied by the electric machine is performed by processing data detected by the direct voltage sensor, by the direct current sensor and by the position sensors, respectively, in the previous third step and first step, and parameters of the electric machine; and
in the sixth step, a comparison is performed between the check torque value computed in the fifth step and the estimated torque value estimated in the fourth step, to verify that a difference between the two values is lower than a pre-set value.
