Abstract
A high accuracy magnetic rotary encoder for the speed sampling is designed, including both the hardware structure and the magnetic field analysis. For improving the magnetic field distribution of a magnetic encoder and lower the harmonic of output signals, the hardware structure with the magnetic collector is proposed. Aiming at decreasing the output deviation of the magnetic encoder, the signal correction algorithm based on the least squares estimation is put forward. In order to achieve an accurate measurement of a rotor velocity and a position, the signal decoding algorithm based on the closed-loop position tracking system is designed. The simulation and experiment results are provided to demonstrate the effectiveness and practicability of the proposed method.
