摘　　要：设计了一种基于高精度数字解码RDC芯片的伺服系统角度位置信号解调方法。在阐明旋转变压器获取伺服系统角度位置信号的工作原理后,着重介绍了系统的实现方式,并对几种设计思路进行对比,提出性能较优化的设计方案。与此同时,分析了本设计的误差源,并根据分析设计出相应的抗噪及驱动电路,用以提高系统的稳定性和可靠性,最终通过Multisim进行仿真。An angle and position decoding scheme based on high precision RDC chip is traduced in this paper.In this scheme,the rotary transformer is used to obtain the angle position of servo system.The AD2S1210 is used to decode the angle and position signal of rotary transformer.In this paper,the principle of rotary transformer and the circuit of RDC by FPGA and DSP is mainly introduced.By comparison,the high frequency noise is eliminated by this method.Simultaneity,The High Current Drive technique is used to achieve the ideal driver current.The simulation conclusion of Multisim shows that this method can provide an effective decoding circuit for resolver signals with high reliability.
