Compound control system design based on adaptive backstepping theory

Combat environment for air-defense missile is very complex, for example, high-speed and high- maneuverability. Reaction-jet and aerodynamics compound control and guidance technology is the crucial problem of air-defense missile control and guidance system design. The control law and guidance laws for reaction-jet and aerodynamics compound guidance missile were investigated. A control method based on adaptive backstepping theory was put forward for the non-linear system. Fuzzy logic was applied to the design of compound steering law. A variable structure guidance law was proposed for 3-D terminal interception. Taking an anti-air missile as an example, simulation results show that the guidance and control system is easy to realize and has fine guidance precision for a high-speed maneuvering target, and it proves the effectiveness of the method.
