摘要
通过鉴别感应同步器激磁信号和感应信号的相位差来检测感应同步器的转子相对定子的角度.采用Actel的Fusion集成的FPGA、A/D转换和CoreMP7的ARM7内核,实现正、余弦信号的产生、数据采集和数据处理的单芯片SOC系统,同时,在激磁信号0°相位时采集感应信号,通过FFT计算感应信号的初相位,进而实现感应同步器的位置检测.
This paper detects the angle of rotor relative to stator through identifying phase difference between excitation signal and induction signal of inductosyn. The FPGA, A/D converter and ARM7 kernel of CoreMP7 integrated with Fusion chip of Actel realizes the generation of sine and cosine signals, data acquisition and data processing. At the same time, induction signal is acquired when excitation signal phase is 0°, and then initial phase of induction signal is calculated by FFT, thereby realizing angular position detection through inductosyn.
