Abstract
According to various embodiments, a motor control unit is described which includes an estimating circuit configured to implement a state observer and an input configured to receive measured values representing a sequence of motor shaft angles of a motor and supplying the measured values to the state observer, wherein the estimating circuit is configured to perform an estimation of the motor shaft angle and / or the motor shaft speed by generating, using the state observer, a time series from the measured values representing motor shaft angle estimates, motor shaft speed estimates, or motor shaft angle estimation errors, filtering the generated time series by a machine learning model with an autoencoder architecture, and generating one or more estimates of the motor shaft angle and / or the motor shaft speed from the filtered time series.
