地空导弹制导控制系统仿真设计、验证和确认

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.

Design, Verification and Validation of Guidance and Control System Simulation of Ground to Air Missile Weapon System

The guidance and control system simulation of ground to air missile weapon system is from the beginning to the end of guidance and control system development. The design, verification and validation of simulation software are related to simulation rationality, correctness and high-efficiency. With a view to engineering application, a modular software design idea and mixed programming method was introduced by the simulation tools of Fortran and Matlab/ Simulink, simplifying the mathematics model and unifying the calculation step, and primarily completing the simulation model design. The complete program was checked on this basis and the correctness of the computing results was primarily judged. Then the simulation model was verified by manually double calculation and functional check. Finally, the simulation model was validated through a subjective method of comparing the simulation results and real flight test results, Their Inequality Coefficient (TIC) method, and statistical test including static consistency check of ranked sum test and dynamic consistency check of power spectrum estimation, consequently solving the problem of simulation software design, verification and validation.
