摘　　要：针对工程实践中系统状态信号及其高阶微分量提取受测量噪声干扰的问题,分析了DESO(Differential Extended State Observer)滤波器的原理和数学表达式,在此基础上,采用TMS320F2808为控制核心,辅以相应的信号采集、数据传输和参数设置电路,设计了基于DSP的DESO滤波器。测试表明:所设计的硬件DESO滤波器具有良好的滤波和微分提取功能。最后将其应用于坦克炮控系统的状态提取中,为抑制噪声干扰和进一步提高炮控系统的性能奠定了基础。Aiming at the disturbance caused by measure noise in the process of status signal and its differential coefficient collection,the theory and math equation of DESO (Differential Extended State Observer) is analyzed in this paper,on the basis of that,the DESO filter based on DSP is designed,which is centered around the TMS320F2808 assisted with circuit of signal collection,data transmission and parameter setting circuit.The experimental results show that this system has sound performance of signal filter and ...
