Title Research on Guidance and Control Technology for Guided BombAbstract Abstract Modern warfare puts forward much higher performance demand of weapons.It is becoming more and more important in the research field of weaponsthat how to improve the performance of conventional weapons on the premiseof saving costs. Based on the aviation bomb guidance improvement projectas the background, this paper involves the guidance and control technologywhich consists of guidance law design, control loop design and simulationtechnology.Firstly, the mathematical six freedom model of guided bomb isestablished based on its pneumatic characteristics and motive properties.In the following, on the basis of analyzing the existing guidance law andthe 6 DOF mathematical model of guided bomb, this paper optimizes thedesign of project ballistic trajectory which meets the tacticalrequirements.Finally through the use of Matlab programming and simulation test thereliability of trajectory design and control technology are verified.
Keywords: Guided bomb Project ballistic trajectory Flying controlControl loop
