METHOD FOR DYNAMICALLY DETECTING AN ANGULAR VELOCITY USING A DIGITAL ANGULAR POSITION TRANSDUCER

摘要

The invention relates to a method and to a device for detecting an angular velocity by way of a digital angular position transducer, for example for controlling an electric motor. Instead of taking into account discrete temporal changes directly in the form of jumps in the output signal, only the portion of the detected angular velocity changes that are (increasing) are included in the output. This facilitates a smoother profile for not entirely precise sensor wheels with levels of imprecision that otherwise lead to unnecessary reactions by the controls. On the other hand, significant angular velocity changes are directly reproduced so that true accelerations associated therewith are taken into account in the controls.
