发明名称 Rotating structure i.e. rotary disk, rotating angle measuring method for e.g. aircraft, involves determining arc tangent of division in analog manner using specific function, where determined arc tangent corresponds to angle of structure
摘要 <p>The method involves measuring an X-component and a Y-component of magnetic field in an analog manner using a magneto resistive bridge circuit. The X-component and the Y-component are divided. An offset (psi 0) of a rotating angle (psi) of a rotating structure is corrected. An arc tangent of the division is determined in analog manner using a specific function by an analog multiplier, an adder and an operation amplifier. The determined arc tangent corresponds to the angle. A coefficient (a1) is adapted such that an average error is controlled at a measuring interval. An independent claim is also included for a device for measuring an angle of a rotating structure using measurement of X-component and a Y-component of magnetic field.</p>
