Abstract
A method of regulating a rotary machine powered by a voltage inverter receiving, as input a control voltage delivered by a regulator servo-controlling the electromagnetic torque on a reference value, the regulator receiving as inputs the reference value and sat least one sampled signal representative of the torque of the machine, and proceeding at each sampling instant, to predict the torque value at a following sampling instant and to modify the control voltage accordingly. Servo-control of the torque including steps of prior computation of a discrete model of the system comprising the machine and the inverter to establish variation in torque between two sampling instants in the form of a first term that corresponds to free variation of the system in the absence of a control voltage, and a term corresponding to variation of the system under the action of a control signal, and of modifying the control voltage in such a manner as to cause the electromagnetic torque to vary from a value that corresponds to free variation of the torque to the reference value.
