A reconfigurable Direct Control Allocation method

In the event of failure of actuators in an overactuated system a reconfigurable law is required to redistribute and coordinate the control effort among the remaining healthy actuators. In this paper, a modified lookup table based Direct Control Allocation method is proposed for reconfiguration of actuator command, for a single actuator fault, without updating the lookup tables. The proposed method saves both memory as well as time to prepare the tables. The method of reconfigurable Direct Control Allocation is then applied to a satellite launch vehicle model. The simulation results show satisfactory performance of the proposed method in the presence of a single Stuck-at-One type actuator fault.
