Key techniques and development trend of guidance and control for hypersonic vehicle

Guidance and control system design is the key element of flight testing for hypersonic vehicles (HV). Nonlinear equation of dynamics, uncertain environment/propulsion parameter and design constraint of propulsion/structure, these flying characteristics require robust, reliable and adaptive control system. Difficulties in scheme design, digital simulation, manufacture of hardware and hardware-in-the-loop simulation are analyzed, key technologies such as conceptual design of control system, guidance and control law design, hardware development of GNC system and evaluation of ground simulation and flight testing are introduced. Key technologies and research directions deserved attention to in each phase of control system development are viewed.
