摘　　要：提出了一种基于正切算法的轴角数字转换器设计方案,并给出了软硬件实现方法。该方案利用峰值采样和查表求角,解决了正切算法的不连续和溢出问题,比传统跟踪式算法的轴角转换器结构简单,使用方便。The paper proposes a solution of angle converter based on tangent algorithm, 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. Compared with traditional tracking types, the structure of the converter is simple, and it is easier to use.
