双通道旋转变压器解码算法改进

Improvement of Two-channel Multi-pole Resolver Decoding Algorithm

在某型测控设备天线控制单元维护过程中,发现天线转动时方位角存在跳码现象。针对该问题,文中通过分析天线角度采集与解码过程,发现当前所采用二进制组合编码的局限性,进一步对粗精码相位差超出可修正范围时出现跳码的原因进行理论分析,提出了改进的粗极余数与精极值组合算法。理论分析和仿真验证结果同时表明,新算法的纠错能力是二进制组合编码算法的2倍。

Angle jump occurred during the process of rotated of the antenna control unit maintenance. To address this problem, the acquisition and decode process of antenna angle were analyzed to investigate the limitations of the current use of binary combination coding algorithm. In this paper, the reason for the occurrence of code hopping when the phase difference of coarse and fine code exceeded the correctable range was theoretically analyzed, and an improved combination algorithm of rough and residual numbers and precise extremum was proposed. The theoretical analysis and simulation results showed that the error correction ability of the new algorithm was twice that of the binary combination coding algorithm.
