摘要：
In order to improve the accuracy of round inductosyn angle-measuring system, a new error source of the angle-measuring system was discovered, the concept of sector etching error in the round inductosyn angle-measuring system was proposed, then the sector etching error was introduced into the error model of the round inductosyn angle-measuring system, and a perfect angle-measuring system error model was established. The orthogonality and coupling characteristics among the error sources in the limited sampling space were analyzed and a combination test method with different starting angles was designed to separate the error sources. Finally, correctness of the method was proved by comparing the angular position error measurement results with the 23-mirrored polygon-autocollimator measurement system and with the 391-tooth indexing table-reflected mirror- autocollimator measurement system. © 2019, Harbin University of Science and Technology Publication.
