发明名称 METHOD FOR DETERMINING A TWIST ANGLE
摘要 <p>A method for determining an angle between a first shaft section and a second shaft section is provided. The 0° position of the first shaft section is determined by a first shaft signal, and the 0° position of the second shaft section is determined by a second shaft signal. The first shaft signal and the second shaft signal are subsequently each decomposed using Fourier analysis into frequency components of harmonic oscillations, wherein frequencies are calculated for the first shaft signal, and frequencies are calculated for the second shaft signal. The frequencies are each calculated as complex pointers from absolute value and phase of the order thereof wherein each pointer describes the angular velocity of the particular frequency. For each frequency, the particular angle of the complex number is then divided by the order, wherein standardized complex pointers are calculated. The standardized complex pointers are added complexly.</p>
