一种高精度、低成本旋转变压器信号解算器设计

摘要

The resolver angle measurement system have the disadvantage of high cost or low decoding accuracy. A solution for resolver angle measurement system was designed by using the methods of combining signal conditioning circuits and software decoding algorithm, which ensure the decoding accuracy of the system and reduce the cost. The feasibility of the design proposal was confirmed through the Matlab simulation.%针对目前旋转变压器测角系统成本高或解码精度不足的缺点,采用信号调理电路和软件解算算法相结合的方法,设计一种用于旋转变压器信号解码的解算器,该设计在保证测角系统解码精度的同时,又能大大降低成本.最后,采用Maflab仿真软件对该设计方案进行验证,证实了该设计方案的可行性.
