摘　　要：在高性能电机的闭环控制系统中,旋转变压器(简称旋变)常用于测量电机转子的位置与速度信息,设计了一种以专用旋变数字转换芯片为核心的磁阻式旋变解码系统,用于将旋变输出的正余弦信号解码为转子的位置信息。解码系统包括主芯片模块、旋变输入信号调理模块、励磁缓冲电路模块和电源模块等,将各功能模块集成在一块印刷电路板(PCB)上,并通过实验验证了设计方案的有效性。实验结果表明:设计的磁阻式旋变解码系统运行稳定,能实时准确地输出电机转子的位置与速度信息。In closed-loop control system of high performance motor,resolver is often used to measure the position and speed information of motor rotor.A reluctance resolver decoding system based on special rotary digital conversion chip is designed,which is used to decode the sine and cosine signals output by resolver into position information of rotor.The decoding system includes the main chip module,conditioning module of input signals of resolver,the excitation buffer circuit module and the power module.The four functional modules are integrated on one printed circuit board(PCB),and the effectiveness of the design scheme is verified by experiments.The experimental results show that the decoding system of the reluctance resolver runs stably,and can accurately output the position and speed information of the motor rotor in real time.
