摘　　要：针对现代先进飞机的多操纵面气动布局和传统特征结构配置方法(EAM)设计控制律时存在的问题,提出了一种基于EAM的多操纵面控制分配设计策略。通过模块化设计,使控制律与分配律分别独立设计。首先,基于传统EAM设计三轴指令跟踪控制的传统控制律,得到三轴虚拟控制指令。然后,用控制分配方法对多操纵面进行协调分配,发挥冗余操纵面的潜力。仿真结果表明,与传统EAM相比,基于该策略所设计的多操纵面飞机飞行控制律,不仅能快速、准确地得到期望的响应信号,还能很好地分配各个操纵面,达到了良好的控制效果,表明了所提出方法的有效性和快速性。Aiming at the problems existing in the design of control law for modern advanced aircraft with multi-control plane aerodynamic layout and traditional eigenstructure assignment method(EAM),a multi-control plane control allocation design strategy based on EAM is proposed.Through modular design,the control law and the distribution law are designed independently.Firstly,the traditional control law of three-axis instruction tracking control is designed based on traditional EAM,and the three-axis virtual control instructions are obtained.Then,the control allocation method is used to coordinate the multi-control plane and exert the potential of redundant control surfaces.The simulation results show that compared with the traditional EAM,the flight control law designed based on the strategy,multi-control plane can not only quickly and accurately obtain the desired response signal,but also allocate various control surfaces,to achieve good control effect,which show the effectiveness and quickness of the proposed method.
