一种多操纵面复合控制的动态分配策略研究

随着航空航天技术的迅速发展,现代飞行器常采用多种操纵面进行控制,以提高飞行性能。基于多操纵面控制的姿态控制系统,需要将控制量在各操纵面之间进行分配。然而由于不同操纵面的执行机构在摆角范围、舵面效能、负载特性等多个方面存在差异,单一的分配策略难以实现姿态控制系统的综合性能最优,甚至会影响到控制系统的稳定性。针对上述问题,提出了一种适应多种约束要求的目标函数构造方法,并在此基础上,研究了自适应动态加权最优分配策略,最后通过数学仿真试验对比验证了该分配策略的有效性。

Research on Dynamic Allocation Strategy for Multi-Effectors Compound Control

The modern aircraft usually adopts different kinds of effectors to improve the flight performance. For attitude control system with multi-effectors compound control,it is necessary to allocate the control quantity properly to multi control surfaces. However,due to the difference of the multi actuators in the angular range,rudder effect and load characteristics,it is difficult to achieve the optimal attitude control performance and ensure the stability using the single allocation strategy. In order to solve the above problems,firstly,an approach is presented to construct the objective function with multiple constraints. Then an adaptive dynamic weighted optimal allocation strategy is proposed. Finally,the effectiveness of the allocation strategy is verified by mathematical simulations.
