Abstract
A method for controlling a reluctance machine, particularly a switched reluctance machine by use of a torque controller, in which motor windings are switched on as a function of the rotor angular position (&ggr; ) at a switch-on angle (&ggr; ) and are switched off at a commutation angle (&ggr; ) , with the angles being determined as control parameters (i , &ggr; , &ggr; ) , as a function of the rotation speed (n) from stored control coefficients (&ggr; ,c , m , c , c , c , M , p, q) which are read during operation of the reluctance motor, with the commutation angle (&ggr; ) for each rotation speed (n) at least remaing constant or increasing, starting from a maximum value c at a maximum totque (M ) , as the torque values (M ) decrease, and , subsequently, with a winding current preset nominal value (i ) , which is claculated as a control parameter, for the windings (A, B, C) of the reluctance motor being sent to a current regulation device.
