摘要
为提高测角精度,通常使用双通道多极对旋转变压器组成高精度测角系统。针对已有该类测角系统的角度组合算法进行了分析研究;在已有角度组合算法和角度组合中误判的原理基础上,提出了两种角度组合算法:最大纠错组合算法和特殊条件下的二进制组合算法,前者具有最大纠错能力,后者在特定条件下实现简单快速。数字仿真和实际系统中的应用结果,均验证了文中算法的有效性。
To enhance the angle measurement precision, two-channel multi-pole resolver is usually used in high precision angle measure system. The angle combination of two-channel multi-pole resolver was studied for a uniform method. According to the analysis of the existing combination algorithms and theoretical error judgment, two kinds of relevant algorithms were presented, which were most error-corrective method, binary combination method under special condition. The first method has the most correction capability and the latter one can be achieved simple and expeditious. The results of both digital simulation and applications in practice system validate the alzorithms.
