【Abstract】 The control accuracy, performance, system architecture, and flight reliability of the new generation large launch vehicle Long March 5(LM-5), has reached the international advanced level. The key technologies of LM-5 control system are systemically introduced, as known as the high thrust accurate guidance control sending over 20 tons payload directly into orbit, the interplanetary strong adaptive guidance control covering the Earth-Mars transfer orbit with second cosmic velocity, the combined swing control of booster and core stage multiple heterogeneous engines for thousand-ton launch vehicle et al. These achievements have filled the domestic gap and greatly enhanced China’s ability to enter space independently.更多还原
