本文试图利用直接频率合成技术为某型航空发动机电子调节器综合测试系统提供信号源。基于对象特性,本文只产生中心频率为1080Hz,频率范围为1080±5Hz,步进为0.1Hz的正弦信号。主要是通过MCU接受PC机控制指令,实现对FPGA的控制,从而产生出所需的信号,并且实现对输出信号的控制。本文所述的方案具有精度高,成本低的特点。
This paper attempts to use direct frequency synthesis technology for a type of aeroengine electronic regulator integrated test system provides a signal source. Based on the characteristics of the object, this article only produces a sinusoidal signal with a center frequency of 1080Hz, a frequency range of 1080 ± 5Hz and a step of 0.1Hz. Mainly through the MCU to accept PC control instructions to achieve the control of the FPGA, resulting in the desired signal, and to achieve the control of the output signal. The solution described in this article has the characteristics of high precision and low cost.
