Reconfigurable control allocation of multi-surfaces aircraft based on improved fixed point iteration

For the real-time requirement of reconfigurable control allocation problem in the field of multi-surfaces aircraft, the control allocation scheme based on max direction derivative increment (MDDI) fixed point (FXP) iteration is proposed. The increment update for current iteration along the MDD and the design steps are given. Moreover, the convergence of the improved method is also proved. Comparisons of different methods are simulated in multi-surfaces aircraft model. The simulation results show the rapidity of MDDIFXP method compared with the original one and the effectiveness of the method in solving reconfigurable control allocation problem of multi-surfaces aircraft.
