摘　　要：通过硬件解码的方式解出旋变的输入信号,虽然该方法能够较快较准确地解算出旋转变压器的输入信号,但相应增加了成本投入。在实际应用中常采用软件解码以节约成本。文章通过simulink建立了模拟的正余弦信号发生器,通过区间判断和区间选择,使用不同的tan和cot值。并且解决了正余弦相除在算法运行中报错问题。在excel中制作了相应的正余弦值对应的实际角度值导入到matlab中。基于磁阻性旋转变压器的位置检测,设计出了一种基于反正切查表的位置检测方法,并在simulink仿真平台上进行了仿真验证该算法的合理性。The way of hardware decode for resolve can decode the signal input from the resolver, but it increases the investment in the equipment. In practical usage, the software decode is being commonly used. In this paper the simulated sine and cosine signal generator is established to solve the problem of error in the operation of the algorithm. Through the interval judgment and interval selection, use different tan and cot values.In the excel the corresponding cosine and sine value is produced. Based on the position detection of magnetoresistive resolver, a position detection method is designed. The rationality of the algorithm is verified bythe simulink simulation platform.
