Redundant Inertial Measurement Unit Reconfiguration and Trajectory Replanning of Launch Vehicle (eBook)

This book analyzes the problems to be solved urgently in the development of launch vehicle control system. The techniques of redundant Inertial Measurement Unit (IMU) reconfiguration and trajectory replanning are proposed aiming at the inertial device failures and power system failures during flight of launch vehicles, respectively. It introduces the background of redundant IMU reconfiguration and trajectory replanning technologies and models of launch vehicle dynamics and redundant strap-down IMUs. The approaches for redundant strap-down IMU fault detection, reconfiguration and trajectory replanning are proposed, putting forward a prospect for the development of launch vehicle control system. The content of this book is concise and highly pragmatic. It could serve as a reference for engineers and researchers engaged in the analysis, design and verification of launch vehicle control systems and also as a reference for graduate students and senior undergraduates majoring in navigation, guidance and control.

Fan Xu is a researcher at Beijing Aerospace Automatic Control Institute, graduated from Northwestern Polytechnical University in 1999 with undergraduate degree and Beijing University of Aeronautics and Astronautics in 2009 with Ph.D. He is now mainly engaged in research on autonomous navigation, online planning and guidance control technologies for launch vehicles.
