| titleOfInvention | A kind of signal processing method of magnetoresistance transformer |
| abstract | The invention discloses a kind of signal processing method of magnetoresistance transformer, it is used for two pairs of output signals of two output windings for handling magnetoresistance transformer.The signal processing method first ensures that two pairs of output signals are all synchronized with defined shake in processing；Then two low frequency signals of extraction are corrected, the phase deviation of two correction signals, the final electrical angle instantaneous value obtained in the electrical angle cycle is corrected by the trigonometric function operation to cos (θ)；One special angle is obtained from electrical angle instantaneous value according to mechanical angle zero position reference point signal, the special angle is converted into respective rotor position mechanical angle, mechanical angle carries out negative-feedback to produce angle th with system perspective error compensation amount, and angle th is calculated through speed and obtained angular velocity omega.The present invention can improve the angle th of magnetoresistance transformer precision and the precision of angular velocity omega. |
