摘要
介绍了一种制导炸弹弹道仿真系统的开发过程。主要分为两部分:一是建立了用于仿真的弹道计算模型,环境模型和制导控制模型;二是论述了系统开发的实现方法及相关技巧。首先,采用非线性变系数微分方程描述弹道计算模型;设计制导控制模型使得该弹道仿真系统具有较强的通用性;建立较为完整的环境模型,对目标点没有特别要求,可用于制导炸弹打击近程(远程)地面固定(移动)目标的仿真。其次,以Simulink构建弹道仿真系统,应用多速率仿真及Real-Time Workshop技术提高仿真速度。最后,给出制导炸弹的弹道仿真实例,表明模型可用。
The development of ballistic trajectory simulation system for guided bombs was proposed. The task is divided into two parts. One is to constitute trajectory model, environment model and guided ＆ control model. The other is to discuss how to realize these models in program languages or software. Firstly, a nonlinear variable coefficient differential dynamic model was constituted to describe the motion of guided bombs. The guidance ＆ control model could be easily modified to represent different guidance and control methods. And a complete environment model was used. Hence, the simulation model was capable to accomplish the simulation of attacking different targets. Secondly, Simulink was utilized to realize the trajectory simulation model. In order to improve simulation efficiency, the Techniques of Multiple rate transition and Real-Time Workshop （RTW） are used. Finally, a trajectory simulation test was done based on a certain type of guided bombs. The simulation data are comparative to those from shooting range, and the results prove the model to be usable.
