ABSTRACT Three-axis flying posture simulator is a set of precise and sophisticated equipment with important significance of economy and national defence. TFPS is a kind of powerful instrument used to reproduce the flying posture of flying weapons in laboratory. TFPS, together with equipment producing infrared target, simulates the attacked target and flying missile, which can really simulate the various flying postures in space and dynamic characteristics. Thus, the performances of sensors, control system and actuator and so on can be tested and evaluated, which provides various reference bases for developing, improving and redesigning flying weapons.

To overcome the bad effect resulting from the nonlinearity time-variability and uncertainty on autopilot system performance during the motion process of aerodynamics missile, and to further improve the flight quality of missile, the autopilot system and used control method are researched. Firstly the integrant structure of system is discussed; then baaed un introducing the traditional PID method, controllers for missile attitude motion are designed respectively using fuzzy self-turning PID method and neural network self-adaptive PID method; at last a simulation experiment is finished. By comparing the simulation results that the designed controllers have good qualities is showed, and the feasibility and validity of applying fuzzy control and neural network into automatic control of aerodynamics missile is confirmed, and the base that other nonlinear control theory can be combined with the traditional control for missile to further improve the performance of missile control system is established.
