| 英文摘要: |
| In order to improve the accuracy and safety of the position detection of the transmission system and to reduce the position deviation, the dual
position solving method of absolute photoelectric encoder and resolver was proposed. Based on the high speed chip TMS320F28377S, communication circuit of absolute photoelectric
encoder and DSP was designed, the SCI module was used to communicate with the encoder; the interface circuit between the resolver and the DSP was designed, and the output signal was
sampled over 160 times and phase sensitive was rectified; The encoder and the resolver were installed at the first and end of the transmission system respectively, and the position solving
results were verified mutually, ensuring the correctness and safety of the position. The experiment shows that the method can detect the position quickly and accurately, and can improve the
system′s performance. |
