Evolution of the Robust Control Design for the M-V Launch Vehicle
The M-V launch vehicle is the worlds highest performance solid rocket system which has contributed to even planetary missions. The paper puts emphasis on the evolution of the robust control design for the M-V rocket since its first flight in 1997. To get appropriate robust stability ,H∞ control theory was adopted in its development period of early 1990s when no one could see any other challenge to apply the post modern control theories to launch vehicles over the world. Its performance was verified by the first three flights of the vehicle conducted in 1997,1998 and 2000. Beyond this established control algorithm, the control design was further upgraded to enhance its robust characteristics in 2003 for the M-V-5 launch which successfully injected an asteroid sample return spaceship into its interplanetary trajectory. This vehicle had the second stage renewed to have higher pressure propulsion and more versatile mobile nozzle system. This prompted robustness design even in tracking performance because the mobile system has slower response and greater uncertainty in its dynamics than the former liquid injection type. Thus the control design evolved to the more sophisticated μ-synthesis, which was applied for the first time ever to Japans launcher control to get robust characteristics not only in stability but in tracking performance. The effectiveness of the design methodology was established by the last four launches of the vehicle executed in 2003 ,2005 and 2006(twice).
