摘要
A method for compensating interference in a measured angle signal of a magnetic angle sensor of an electrical machine, wherein the method includes: receiving a measured angle signal, estimating a current error and/or a misalignment error in the measured angle signal, calculating an expected rotor angle from the measured angle signal, taking into account the estimated current error and/or the estimated misalignment error, such as during operation of the electrical machine. The present invention furthermore relates to a microcontroller for calculating interference in a measured angle signal of a magnetic angle sensor of an electrical machine, to an electrical machine having a magnetic angle sensor and a microcontroller and to a computer program product.
