| 摘 要： | 提出了一种基于FPGA的双通道旋转变压器测角电路设计方案,通过FPGA来控制AD2S82A、AD2S80A的解码和同步问题。同时用FPGA对转换后数据进行误差补偿和组合,以及二进制角度值的转换,提高了整个系统的集成度和可靠度。整个电路在Altium Designer 9.0设计环境下设计实现。采用Altera公司的EP2C35F484C6型FPGA芯片进行FPGA部分的仿真,实验和仿真的结果很好地实现了该方案的设计功能,并满足高精度、高速度转换的设计要求。

| Abstract: | A design scheme of angle measurement circuit for two-speed resolver based on FPGA is introduced,which controls the decoding and synchronization of AD2S82A and AD2S80Athrough FPGA.The error compensation and combination of the converted data and the conversion of binary angle value were carried on by FPGA,in order to improve the integration and reliability of the whole system.The whole circuit was designed in Altium Designer 9.0 design environment.The simulation of FPGA part is based on the chip EP2C35F484C6 of Altera Company,the test and simulation results achieve the design functions of the scheme commendably,and meet the requirement about high-precision,high-speed conversion of the design. |
