In order to develop an intelligent guidance and control system, which can increase the mission robust performance in the full launch cycle, this paper provides the launch vehicle fault modes, and presents a fault classification method based on the energy characteristics firstly. The function and performance requirements to the guidance and control system are put forward for different ranks of energy fault. Especially, for the small and medium energy faults, the self-adaptive guidance methods, including the case and orbit-changing principle, are introduced;besides, the ways of implementation for the applications of the self-adaptive guidance technology are discussed. The fault classification method based on the energy characteristics and the self-adaptive guidance method can be applied to the future launch vehicles of China.
