Research On The Comprehensive Evaluation Method Of Guided Bomb Guidance And Control Law Performance Based On Mathematical Simulation

In the local war of modern high-tech,guided bomb has become the conventional weapons of importance,which is widely used in recent period.As it's developed quickly,problems,such as high cost and long period of manufacture,come into being,because of the complicated structure of system.Guidance and control law of high performance plays an extremely important effect in making the best use of combat.In the paper,the research for the method of comprehensive evaluation of guided bomb guidance and control law does good to the selection of guided and control law for guided bomb.The background is that some guided bomb carries out the precision strike to the enemy's middle-sized command post.And the research,based on mathematical simulation,is about the comprehensive evaluation method of guidance and control law performance.The main content is as follows:Firstly,make the analysis of comprehensive evaluation method.In the paper,the analysis contains three parts,the index data standardized method,index weighting method and index integrated method,and the stages of research are put forward,all of which lay the foundation for the later research.Secondly,build the index system of comprehensive evaluation and the mathematical simulated program of guidance and control law,and do research into the approach of gaining index original data.The index system is established,concluding guidance law performance and control law performance,based on mathematical simulated program and data.According to the research background and the character of guidance and control law,the simulated program of bomb body and two projects are built.The bottom index is devided into three categories according to the approach of gaining index original data,and according to simulated data,calculation method for each kind of index is discussed together with examples.Thirdly,carry on the deep research on the index data standardized method,index weighting method and index integrated method.Corresponding standardized function is dicussed according to the index category,and examples of classical function are put forward.On the basis of common weighting method,the index weighting method is discussed with reality,and the examples are also provided.The index is integrated via the approach of variable weight synthesis.Meanwhile,the examples and analysis are given.At last,compute the comprehensive evaluation result and make the analysis of the comprehensive evaluation method.The corresponding evaluation result for two projects is calculated and the analysis is made for the result.And combining with the evaluation result the comprehensive evalution method is analyzed from the feasibility,effectiveness,and general applicability.
