Zhuangzhi Han, Heng Zhang, Qiang He, Chaoxuan Shang · 2009
The paper proposes a solution to digitize the angle information of the two speed resolvers based on tangent algorithm. This solution is simple than the tracking types in common use. The principle is analysed and the configuration of software and hardware is presented. To avoid overflow and improve precision, sampling at the signal peak and two tables are adopted. The experiments show that the solution is steady, reliable, high-accuracy, and low-cost.
