USING COMPUTER SIMULATION AND SYSTEM IDENTIFICATION METHODS-TO CALCULATE THE TRAJECTORY OF MISSILE

摘要: 提出了求解某武器系统导弹弹道轨迹的两种方法：计算机仿真和系统辨识方法．详细介绍了导弹系统的计算机仿真模型，并利用控制理论和数值分析的方法对仿真模型求解；根据系统辨识理论，将整个系统看作“黑箱”，建立与输入、输出数据等价的模型，引入折息因子对模型进行辨识．最后分别给出了计算机仿真试验曲线和系统辨识试验曲线，证明了两种求解方法的有效性．

Abstract: This paper proposed two methods,computer simulation and system identification to calculate the trajectory of missile.The simulation model which can be solved according to cybernetics and numerical analysis was described in detail.The whole system can be regarded as a "black box" based on the theory of system identification,the equivalent model of input and output was established,and the discount factor was introduced to recognize the model.Finally,the experiment results about simulation and identification are given respectively and the effectiveness of the two methods was proved.
