摘要： A control system included in a speed selector connected by output phases to a synchronous electric motor, the synchronous electric motor being controlled according to a control law implemented by the speed selector. A first speed of the synchronous electric motor is determined by a first speed estimator. A second speed estimator is used to determine a second speed of the synchronous electric motor. The system includes a signal generator module configured to apply, to the output phases, voltages taking account of a non-constant current signal. The second speed estimator is configured to recover the current response on the output phases, to deduce therefrom the second speed of the synchronous electric motor.

摘要： A method for controlling a variable speed drive comprising Ni low-voltage power cells connected in series for each phase among multiple phases, i being a phase index. The method comprises repeating P iterations comprising: activating at least one cell of one or more phases and deactivating the other power cells of the variable speed drive, wherein the at least one activated cell is selected on the basis of predefined activation controls depending on an iteration index; and receiving at least one output voltage of the variable speed drive across the terminals of the electrical device for at least one phase. The method further comprises, at the end of the P iterations, determining, from the measured output voltages, values of rectified voltage at the output of respective rectification stages of the power cells, and storing the rectified voltages obtained, which are respectively associated with the power cells.

摘要： Examples include a method for controlling a variable speed drive of an electric motor. The variable speed drive is connected to a torque sensor for sensing a torque supplied by the electric motor. The method includes performing, by the electric motor, a predetermined torque sequence.
