在使用不同长度电缆对平台系统测试时,出现姿态角传感器角度输出有较大变化的现象,作者通过大量试验,并从姿态角传感器的工作原理和特点分析,得出长电缆会对姿态角传感器粗通道产生常值偏差的结论,同时根据产生常值偏差的机理,提出在长电缆末端并联移相电容消除长电缆对姿态角传感器影响的措施,并通过试验验证了此措施有效可行。

The bias of attribute resolver varies with different length cables during platform tests. By analysis on principle and characteristic of attribute resolver and a lot of test data, theconclusion is obtained that additional constant bias of attribute resolver coarse channel would result form the long length cable. Capacitor parallel at the end-term of long cable can eliminate the additional const bias, and test results have approved that the approach is avaiable
