Abstract
Apparatus and method for controlling the electromagnetic torque of an asynchronous machine. The apparatus includes a corrector which controls the electromagnetic torque of an asynchronous machine by regulating the magnetic flux and by controlling the electromagnetic torque C.sub.m, the corrector including a regulator circuit (3) for regulating the rotor magnetic flux .phi..sub.r , having non-linear control using input/output linearization by static looping and whose output controls the d-component of the stator current i.sub.s, a first linear corrector (1) of the proportional, integral type whose output v is the input to the regulator circuit, and a second linear corrector (2) of the proportional, integral type whose output controls the angular frequency of the rotor currents .omega..sub.s1.
