| To provide lift,the glide guidance bomb uses high aspect wing or diamond back wing,and it can achieve long-distance flight without power,with the abilities of low cost,precision strike capability,stand-off launch and combat airspace.At present,the United States,Europe,Israel,South Africa and other countries are developing the series of glide bombs,there is also number of units of the glider bomb in our country.As glide bombs with UAV technology matures,they play an important role in the recent local wars in the world,considering the cost efficiency,and it promotes the rapid development of unmanned airborne guided bombs.The guidance and control system is designed for the airborne glide guidance bomb.Because of the interference of the wing and lug,the bombs hang upside.In view of the turning control,the singularity of BTT control command and Elastic vibration suppression,analysis and demonstration are carried out.Angular velocity and angle control is adopted for the rolling channel,and overload control is adopted for pitch and yaw channels,the singularity is proposed to be solved by mixed BTT/STT guidance strategy.Based on the test data,the elastic vibration filtering method is given.The guidance and control law and the emission region are also designed in the paper,and results show that the design is reasonable and feasible,meeting the bomb delivery and use requirement,having high practical value.Finally,the work is summarized in the paper,and the design of the guidance and control system is prospected for the future. |
