Abstract

For electric vehicle applications, three phase electric machines like permanent magnetized synchronous machines and induction machines are the preferred choice. These machine types are controlled by the field-orientated control concept in general, whose high torque quality is an important performance criterion. For applying the field-orientated control, usually rotor position sensors are used to perform the necessary transformations from a stationary reference frame into a rotating reference frame and vice versa. These absolute position sensors can also be utilized for generating a speed signal for speed control purpose, since integrating an additional speed sensor increases costs, complexity and fault liability. There are different kinds of sensor principles for automotive applications available, which differ significantly in their accuracy and error characteristics. These sensor errors take impact on the speed signal generation and therefore on the torque and speed control behaviour of the applied electric machines. This paper focuses on the induced disturbances from rotor position sensor error signals regarding speed ripple and control activity considering two different methods of speed signal generation.
