Side Jet And Aerodynamics Compound Control,Guidance And Simulation Of Intercept Missile

This paper mainly works on the problem of modeling, control and guidance for a side jet and aerodynamics compound control intercept missile.Partâ… , study the model of side jet and aerodynamics compound control intercept missile. This paper refers the figures and dates of some missiles in domestic and foreign, builds the aerodynamic date, engineer and rudders mathematic model, analyses the phenomenon of side jet interaction with external flow, builds a side jet model with append factor which conforms to the actual situation, and founds nonlinear mathematic model of this missile.Partâ…¡, study the control problem based on layered structure. The control system of missile is divided into three layers, which exploited the different time scales of the missile dynamics. Because there may be some errors in the control, we can use on-line neural network to compensate these errors. Through command resolution procedure, compound control is realized, and the effects of compound control and pure aerodynamic force control are compared, the validity of compound control is proved.Partâ…¢, study the guidance law of the terminal guidance section. A kinematics model for 3D guidance problems is derived, a new kind of nonlinear variable structure adaptive guidance law is brought up by researching the variable structural strength item, and another fuzzy variable structure guidance law with self-adapt region is realized to enhance robustness of target acceleration estimate error of guidance law.Partâ…£, on windows platform, this paper use VC++ and OpenGL to develop 3D-visualization intercept missile platform, which can show the process of missile intercept target vividly.
