Abstract (en)
[origin: WO2011070391A1] In a method for estimating the angular position (ß) of a rotating device (13, 16) with respect to a stationary device (14, 17), first and second signals which represent the angular position (?) of the rotating device (13, 16) with respect to the stationary device (14, 17) are generated. The first and second signals are phase shifted by approximately 90°. A scaled first signal is generated by multiplying the first signal by a first scaling factor, and a third signal is generated by adding the scaled first signal to the second signal. The first scaling factor is chosen such that the phase shift between the first and the third signals is 90° with better accuracy than the phase shift between the first and second signals. The angular position (?) of the rotating device (13, 16) with respect to the stationary device (14, 17) is estimated by utilizing the first and third signals.
