titleOfInvention | A kind of signal processing system of magnetoresistance transformer |
abstract | The invention discloses a kind of signal processing system of magnetoresistance transformer, it includes two A/D change-over circuits, two over-sampling circuits, signal processing circuits.Signal processing circuit includes high stability oscillator, synchro detection circuit, displacement gain-phase compensation circuit, system perspective error correction circuit.Synchro detection circuit extracts low frequency signal respectively according to the recovered carrier signal of oscillator from two trajectory signals of two over-sampling circuits, then it is added by shifting gain-phase compensation circuit with a corrected value, is multiplied and realizes that the correction of skew and gain obtains two correction signals, and the phase deviation of two correction signals is corrected, obtain the electrical angle instantaneous value in the electrical angle cycle.System perspective error correction circuit obtains a special angle from electrical angle instantaneous value, and it is converted into a corresponding rotor-position mechanical angle, mechanical angle and a system perspective error compensation amount carry out negative-feedback to produce angle, and angle calculates through speed and obtains angular speed. |
