CONTROL DEVICE FOR AN ASYNCHRONOUS ELECTRIC MACHINE, ELECTRIC PROPULSION SYSTEM COMPRISING SAID DEVICE, AND METHOD FOR CONTROLLING AN ASYNCHRONOUS ELECTRIC MACHINE

摘要

A control device for an asynchronous electric machine comprising a first computing unit configured for defining a first signal, indicating a desired slip frequency of the electric machine, as a function of a second signal correlated to a reference input velocity supplied through a user interface, and of a third signal correlated to a detected rotor angular velocity, the control device preferably comprising a user interface for supplying the second signal and a velocity-detection module coupled to the electric machine for supplying the third signal.
