【摘要】 对目前高炮火力控制系统目标滤波与预测进行了分析与研究.在此基础上结合工程实际设计了一种α-β滤波器,该滤波器的原理是把在连续系统中频率域的要求和在离散系统中Z域的要求转换成时域中在典型信号激励下的时间响应的特征值的要求,从而在时间域中以特征值的要求进行综合,再把综合的结果转换回Z域中,最终得到所确定的α-β滤波器.文中给出了α-β滤波器的Z传递函数,分析了α-β滤波器参数的确定,对α-β滤波器的静态误差进行了研究,对设计方案进行了计算机仿真和实际应用.更多还原

【Abstract】 The paper analyses and studys the technology of filter and forecast current fire-control system of antiaircraft artillery. A kind of α-β filter was designed. It converted the requirement of frequency-field in series systems and Z-field in discrete systems into the requirement of eigenvalue of response based on typical inspirit. We can integrate the requirement of eigenvalue in time-field, converte the result in Z-field and ascertain the α-β filter. This papershows the transfer-function of the kind α-β filter,analyses the parameters,discusses the static error,and realizes the emluator for the design.更多还原
