现代战术导弹已成为包括连续系统、离散采样系统和离散事件系统在内的混合系统,传统的连续系统建模方法已不适合导弹仿真需求。在对导弹模型中各类动态系统的时间特性和内部结构进行详尽分析基础上,综合运用模块组合和内部模型变换等动态系统建模技术构建了某型防空导弹仿真模型。利用该模型对导弹拦截机动目标进行了统计仿真和结果分析,模型输出的主要运动学参数与该型导弹遥外测数据非常吻合,仿真结果表明上述动态系统建模技术适合作为混合系统的导弹仿真。
Modern tactical missiles have become a hybrid system including continuous system, discrete sampling system and discrete event system. The traditional continuous system modeling method is not suitable for missile simulation needs. Based on a detailed analysis of the time characteristics and internal structure of various dynamic systems in the missile model, a certain type of air defense missile simulation model is constructed by using dynamic system modeling techniques such as module combination and internal model transformation. The model was used to simulate the missile interceptor maneuvering target and analyze the results. The main kinematical parameters of the model output are in good agreement with the telemetering data of the missile. The simulation results show that the above dynamic system modeling technique is suitable for the missile simulation of the hybrid system .
