Air-to-Air Missile Intellectualized Guiding Law And Three Dimensional Animation Simulation Research

This thesis which unifies China air force logistics department advanced research topic–air-to-air missile intellectualized guiding law and the three dimensional animation simulation research, had made a widespread thorough research on air-to-air missile guidance law and control law, and aimed at the two parts of contents to launch a series of research work.First of all, this paper introduced fuzzy guidance law with self-adapt region to the air-to-air missile guidance.Second, a three-dimensional optimum guide algorithm was found out allowing for highly maneuverable targets. Genetic algorithm was also carried out to optimize guidance performance by using MATLAB.Third, this thesis thoroughly had also studied the three-dimensional differential game guidance law. The first-order differential game guidance law expression was inferred based on the linear quadratic differential game theory, the simulation results showed that this differential game guidance law is correct and effective. Moreover, this article also made a preliminary discussion on the combination of neural network theory and the differential game guidance law. The BP model and RBF model and their corresponding learning algorithm were employed to design the neural network guiding rule based on the differential game guidance law.Forth, this thesis also had made a preliminary discussion on the integrated guidance system of air-to-air missile beyond visual range air combat and made deep research on the midcourse guidance stage, thus we obtained an extremely useful conclusion..On the basis of missile six degrees of freedom equation of state, we used the non-linearity dynamic inversion methods to design air-to-air missile basic control law; Next, considered the operation rudder actuator model structure, the anti- integral saturated algorithm and the Smith predictor were used in the actuator control; Finally, the disturbance observer was used to approximate the disturbance of the missile and to on-line compensate the model inversion error.At last, this paper introduced the key techniques of researching and developing real-time 3-D OpenGL missile fight animation software. A 3-D animation simulation software was developed to show vividly the process of air-to-air missile attacking target.
