Observer‐based fault‐tolerant control of hypersonic scramjet vehicles in the presence of actuator faults and saturation

Sign Up to like & get
recommendations! Published in 2019 at "International Journal of Robust and Nonlinear Control"

DOI: 10.1002/rnc.4004

Abstract: An adaptive sliding mode observer (SMO)–based fault‐tolerant control method taking into consideration of actuator saturation is proposed for a hypersonic scramjet vehicle (HSV) under a class of time‐varying actuator faults. The SMO is designed to… read more here.
