The first H-2A Launch Vehicle, the largest launch vehicle in Japan (50 m high and weighing 300 tons) was successfully launched in August 2001. Its control system should accommodate rapidly changing vehicle characteristics as well as structural elasticity and liquid-fuel sloshing. Post-flight analysis showed that the H-2A control system functioned properly. This paper outlines the H-2A control system, vehicle dynamics, stability analysis, and the post-flight telemetry data analysis.
