摘　　要：给出了一种基于现场可编程门阵列(field-programmable gate array,FPGA)的多通道旋转变压器测角系统的设计和实现方案。该方案硬件采用FPGA、数模转换器和模数转换器,软件采用改进型的坐标旋转数字计算算法。测试结果表明,所设计的旋转变压器解算系统的解算精度可以达到±6.3″,解算通道为4个,具有解算精度高、解算通道多的特点。A design and implementation scheme of multi-channel resolver＇s angle measurement system based on field programmable gate array （FPGA） is presented in this paper. In the system, the FPGA, digital to analog converter and analog to digital converter is adopted as hardware, and the improved coordinate rotation digital algorithm is adopted as software. Actual measurement results show that the solution precision of the resolver is ±6.3＂, and the solution channels is 4. These show that the system has the characteristics of high precision and multi-channel solution.
