摘　　要：针对火工品气动压力机在压药过程中表现出的非线性、时变特性,采用了改进的Elman网络——OIF-Elman网络对其进行了动态建模,分析了影响气动压力机压力输出的一些影响因素,并根据实际情况确定了滑动窗式的建模形式。与RBF网络和标准Elman网络相比,改进型的Elman网络具有更好的适应非线性、时变特性的能力,更适用于火工品气动压力机的动态建模。For the nonlinear,time-varying in the course of explosive pressing drug,the dynamic modeling adopting a modifed Elman neural nerwork—OIF-Elman is set up.Some factors influencing the pressure output of pneumatic pressing machine are also analyzed,and the sliding window type of modeling forms is established in accordance with actual conditions.The modified Elman has improved to better meet the time-varying and nonlinear compared to RBF network or the standard Elman network,and is more applicable to the dynamic modeling of explosive pneumatic pressing machine.
