Fault tolerant control based on control allocation for morphing aircraft model

To cope with the fault tolerant control problem of innovative control effectors (ICE) morphing aircraft with actuator fault, employing control allocation method and theory of integer programming, a fault tolerant control scheme based on control allocation was proposed. Firstly, virtual control law was designed to assure that the ICE aircraft can track a desired reference model. Afterwards, the probabilistic fault and saturation constraint of actuators were translated into decision variables constraint of integer programming by the reconfiguration of distributed shape-change effector arrays. In this way, the problem of control allocation was considered as a class of integer programming problem with probabilistic decision variables. To ensure availability and convergence, optimized genetic algorithm was used to solve the problem. Simulation results shows that ICE aircraft with actuator fault also has good tracking performance.
