Abstract
In order to improve the reliability of the absolute-position about grating eddy-current position sensor,three types code word recognition algorithm is proposed and increases the error limit to ±0.1 , through using the complementary relationship of the signal. After using the least square method on the normalized error curve, the errors can be decreased to ±0 . 05 . The experiments proof that the method completely meet requirements of the code word recognition algorithm. And the grating eddy-current position sensor,adopting the technology,could ensure not only the reliability of the absolute-position,but also the stability of the sensor.关键词
