摘要：A method for calibrating a rotational angle sensor having a rotor () coupled to arotating shaft () in a manner which is faithful to the rotational angle, a stator (), and ascanning means () arranged on the stator (). The scanning means () scans a material

measure of the rotor () and generates measured angle values associated with therotational angle position of the rotor (). A laser gyroscope () measures the angularvelocity of the shaft (). The signals from the laser gyroscope () which are dependent onthe angular velocity of the shaft () are integrated over time with respect to the rotationalangle. The measured angle values from the scanning means () are compared withreference angle values, and correction variables are formed from the differences. Duringmeasurement of the rotational angle, the measured angle values are corrected using thecorrection variable.
