RETRACTED: Design of integrated smooth sliding mode of guidance and control for intercepting the hypersonic aircraft

Abstract

A strategy of intercepting the near-space hypersonic aircraft is proposed, which is based on infrared window guidance, change the guidance law from side window constraint to the fixed lead angle, the sliding mode variable structure guidance law with prefix angle constraint is designed. First, setting up the dynamic model for the end of interceptor with direct force/aerodynamic control, deriving the integrated mathematical model of interceptor’s longitudinal guidance and control. Then, by using smooth sliding mode control, the interceptor’s variable structure guidance law with prefix angle constraint is designed. Last, the simulation results show that the designed guidance law can achieve high precision interception for hypersonic vehicle.
