Abstract :
In order to meet the control reconfiguration requirement within a limited frequency range for fault tolerant control systems, a numerical frequency-domain control mixer module method is developed, and the sufficient condition for the existence of a real mixer matrix is obtained based on proper frequency samplings. Furthermore, the heterogeneous control approach is employed to deal with the non-smooth transition problem during the control mixer switches. Finally, a practical self-repairing flight control system is utilized to test our method
