Method of torque control or regulation of electric motor e.g. for motor vehicle steer-by-wire steering system, involves using voltage regulator for controlling voltage output magnitudes of converter in relation to current control

摘要

A method for controlling or regulating a torque (M) outputted from an electric motor (13), in which the current (i1,i2,i3) of the electric motor is subordinated to the torque control or regulation and the electric motor is driven by a converter (15). Using a voltage controller (26) subordinated to the voltage control, the voltage output magnitudes (u1,u2,u3) of the converter (15) are controlled such that they have a specifiable dynamic behavior.
