A computer system is provided. The computer system comprises processing circuitry configured to: for each one of a pre-set positive speed value and a pre-set negative speed value: controlling the speed of an electrical machine to the pre-set speed value, short circuiting the electrical machine, and determining d,q currents and angular velocity of a rotor of the electrical machine during deceleration from the pre-set speed value, and wherein the processing circuitry is further configured to: determining a resolver offset based on the determined d, q currents and the determined angular velocity of the rotor.
