摘　　要：为完善强耦合欠驱动控制飞行器的横向操纵偏航发散参数(Lateral Control Departure Parameter,LCDP)设计准则,详细分析了LCDP对强耦合飞行器稳定性、横向机动效能、滚转通道传递函数的影响,基于LCDP的物理意义建立了强耦合欠驱动控制飞行器应遵循的设计准则建议,结合控制能力、飞行品质与性能指标对设计准则图进行区域划分,阐述了各区域的含义并提出了设计建议。针对某飞行器设计了横航向欠驱动控制器,通过典型状态的仿真结果验证了LCDP对飞行器控制性能的影响及设计准则的正确性。基于LCDP的设计准则为采用欠驱动布局、舵面失效或执行机构故障等具有欠驱动控制需求的强耦合飞行器的设计和优化提供了重要参考。The lateral control departure parameter(LCDP)of strong coupling under-actuated control vehicles is studied and the effect of LCDP on stability,lateral maneuver efficiency and transfer function of roll control is researched in this paper.Based on the physical meaning of the LCDP,a design criteria for strong coupling under-actuated control vehicles is proposed through a figure which is divided into different areas.By illustrating implications of different areas,suggestions of under-actuated control system design for strong coupling vehicles are given.An under-actuated controller for a typical aircraft in different flight states is designed and the correctness of the design criteria is verified through simulation.Design criteria can be used to design and improve the performance.
