Stability analysis and fuzzy control design for near space vehicle re-entry attitude dynamics

This paper investigates a novel composite control scheme of fuzzy control, which is used for near space vehicle (NSV) attitude dynamics during the re-entry phase. For the complicated flight condition during re-entry phase, the Takagi and Sugeno (T-S) fuzzy model is employed to approximate near space vehicle attitude dynamics, on the basis of the linear matrix inequality (LMI) technique and parametric optimization method, the composite fuzzy control algorithms are derived. Unlike earlier studies of fuzzy control systems on an LMI framework, this study develops a supervisory control approach, such that a fuzzy controller can be synthesized more efficiently. Finally, simulation result demonstrates the effectiveness and potential of the proposed technique.
