地空导弹制导控制系统仿真,贯穿制导控制系统研制的全部过程。仿真软件的设计、验证和确认关系到仿真的合理性、正确性和高效性。主要从工程应用角度出发,采用模块化软件设计思想,选择Fortran和Matlab?Simulink仿真工具混合编程,简化数学模型、统一计算步长,初步完成仿真软件的设计。在此基础上,核查全套程序,初步判断计算结果的正确性,然后进行手工复算、功能检查来验证(Verification)模型,最后分别通过仿真结果与实际飞行试验结果相比较的主观方法和Their不等式系数法(TIC法)、秩和检验法的静态一致性检验以及功率谱估计法的动态一致性检验的统计检验方法来确认(Validation)模型,从而较好地解决了仿真软件的设计、验证和确认问题。
Ground-to-air missile guidance system simulation, through the guidance control system developed all the processes. Simulation software design, verification and validation related to the simulation of the rationality, accuracy and efficiency. Mainly from the engineering application point of view, using modular software design ideas, select Fortran and Matlab Simulink simulation tools mixed programming to simplify the mathematical model, a unified calculation step, the initial completion of the simulation software design. On this basis, a complete set of procedures is checked, and the correctness of the calculation results is initially determined. Then, manual verification and function tests are performed to verify the model. Finally, through subjective methods compared with the actual flight test results and their inequalities Coefficient method (TIC method), the static consistency test of rank sum test method and the statistic test method of dynamic consistency test of power spectrum estimation method to validate the model, so as to solve the problem of design, verification and confirm question.
