Obtain antenna angle based on CPLD

针对17位串型脉冲码盘,采用可编程逻辑器件CPLD,对其进行串并转换,再利用译码器,通过并行I/O口,将转换后的17位并行数据传送给单片机,天线闭环传递函数等效为典型二型系统数学模型,经过傅里叶变换离散后,采样周期为50ms,通过单片机8051F040进行计算闭位置环。

For 17-bit serial pulse code disc,a programmable logic device(CPLD)is used to convert the 17-bit serial pulse code disc into parallel one.Then,the converted 17-bit parallel data is transmitted to the single-chip microcomputer by parallel I/O interface with the decoder.The closed-loop transfer function of the antenna is equivalent to the mathematical model of the typical two-type system.For 50ms,calculate the closed position loop through the single chip microcomputer 8051F040.
