Paper Abstract

Future Aero Space Vehicle flies through both the atmospheric and extra atmospheric fields, which implies the autonomy and adaptability to the uncertainties from the system faults and changing environments. Algorithms based on fuzzy logic and linear programming are presented, which can implement the autonomous control reconfigurations under uncertainties via the redundant actuators. The compensation branch minimizes the difference between the desired control objectives and the actual achievable control if the control power is deficient. Otherwise the optimization branch optimizes some sub-objectives by utilizing the excess control power. The fuzzy logic-based regulator tunes the weight vector of the objective functions by the expert rules to obtain the optimized allocation results under various environments with considerations of the control effectiveness. It is illustrated that the algorithms can satisfy the control performance, save the fuel and smooth the allocation output.
