摘 要:为了确保飞机在操纵面故障后的飞行安全,提出了一种结合人工蜂群算法和广义逆法各自优点的重构控制方法。首先,介绍了基于广义逆控制分配方法的基本原理;然后,针对广义逆法存在分配效率较低的问题,采用人工蜂群算法对加权矩阵参数进行寻优,选择较高的转矩可达集体积,以提高基于广义逆控制分配法的分配效率;接着,针对操纵面3种典型故障,推导出对应的重构分配器;最后,通过仿真验证了所提出的控制重构方法能有效地重构飞机操纵面故障。In order to ensure the safety of aircrafts after failure occured in the control surface, a reconfigurable control allocation design strategy that combines advantages of the artificial bee colony(ABC) algorithm and generalized inverse is presented. Firstly, the basic principle of the control allocation method based on the generalized inverse algorithm is introduced. Secondly, since the generalized inverse method has the problem of lower allocation efficiency, ABC algorithm is employed to optimize the parameters of weighting matrix, and the allocation efficiency can be improved by calculating the volume of the attainable moment subset and selecting the largest volume. Thirdly, the reconfigurable control allocators are derived for the typical failures of the control surface, such as deadlock, floating, and damage. The simulation results show that the reeonfigurable control strategy can effectively reconstruct the typical failures of control surface.
