摘　　要：基于追踪型轴角数字转换器(resolver-to-digital converter)设计的绝对式感应同步器测角系统由于输入信号的非理想特性而引入误差,对系统测角精度产生影响。在工程应用中,此类误差可通过电路设计进行补偿修正。在总结绝对式感应同步器测角系统误差来源的基础上,重点分析基于RDC的感应同步器测角系统的工作原理及非理想特性输入误差对测角精度的影响,最后给出电路修正设计。实验表明,通过合理的修正,能够有效的提高系统的测角精度。Non-ideal characteristic input error reduce angle measuring system＇ s accuracy which is designed based on RDC and absolute inductosyn, Reasonable circuit modified can compensate input error and improve accuracy in engineering applications. Based on the summary of the error sources of absolute inductosyn angle measuring system, the analysis of working principle and non-ideal input characteristic input error of RDC were studied. Finally reasonable circuit modified design is proposed. Experiment results show that measuring accuracy would be clearly improved through appropriate circuit modified.
