Abstract EN
For the encoders, especially the sine-cosine magnetic ones, a new method to measure absolute angular position is proposed in the paper.
In the method, the code disc of the encoder has only two circle tracks and each one was divided into N and (N-1) equal code cells.
The cell angles, changing from 0° to 360° between any two neighboring code cells, are defined to represent any position on the code disc.
The position value of the same point can be represented by different cell angle values of different tracks and the absolute angular position of the point can be obtained by the difference value between the cell angle value of the outer track and the inner one.
To validate the correctness of the method theoretically, the derivation process of the method was provided.
An electromagnetic encoder system was designed and the experimental platform was established to test the method.
The experimental results indicate that the electromagnetic encoder can measure the absolute angular position.
Besides, it shows that the method is easy to be realized in algorithm and can reduce computational complexity and decrease dimension of the encoder.
