摘要
传统数模混合电路多道脉冲幅度控制方法输出稳定性不理想,且抗干扰性不强。为此,提出基于FMEA分析的数模混合电路多道脉冲幅度控制算法。构建脉冲信号接收模型,利用均衡滤波器检测信号,结合自相关匹配方法提取脉冲信号特征,通过自相关融合和负载均衡控制的方法,对脉冲信号特征进行幅度检测,采用FMEA分析方法构建脉冲幅度控制模型,实现脉冲幅度的波峰检测和均衡控制。仿真结果表明,采用提出方法进行数模混合电路多道脉冲幅度控制的输出均衡性较好,抗干扰能力较强。
The output stability of the traditional multi-channel pulse amplitude control method of digitalanalog hybrid circuit is not ideal and the anti-interference performance is not strong. For this reason,a multi-channel pulse amplitude control algorithm based on FMEA analysis is proposed. Build the pulse signal receiving model,using the balanced filter detection signal,in combination with the feature extraction of the pulse signal correlation matching method,through the related fusion and load balance control method,characteristics of pulse signal amplitude detection,FMEA analysis method was used to construct pulse amplitude control model,realize the amplitude of the pulse wave detection and balance control. The simulation results show that the output balance and anti-interference capability of the multichannel pulse amplitude control in the digital-analog hybrid circuit are good.
