英文摘要

      According to the online control allocation of a class of distributed driving morphing aircraft with integer control constraints, a solving strategy based on the cuckoo search algorithm is proposed. Firstly, the aircraft online actuator control allocation problem is described as an integer programming problem with the consideration of the command allocation error and effector wear. Secondly, the improved cuckoo search algorithm is designed to obtain the actuator control commands. Some measures, such as the Tent chaos mapping for initializing the population and adaptive step control vector, are adopted to improve the efficiency of the algorithm. Finally, the proposed control allocation method is applied to an innovative control effector aircraft. The simulation results demonstrate the effectiveness of the proposed method.
