摘　　要：机载定向能武器是未来攻防对抗中获得非对称优势的决定性因素之一。针对定向能载荷对目标有效毁伤要求下的面对称飞行器位置、航向、倾斜姿态等多约束问题,提出一种侧向加速度补偿的定向定姿多约束机动制导策略。描述了机载定向能对地面目标实施打击的任务场景,揭示了定向能载荷约束下面对称飞行器的机动规律及其对位置、航向、倾斜姿态等的约束条件;基于面对称飞行器运动学模型及其位置、定向、定姿等多约束条件,设计了“虚拟导引-定姿攻击”的机动制导策略,协调各约束施加的时间和条件,避免了过约束可能导致的指令解算困难问题。分析了各约束条件之间的耦合关联特性,提出了虚拟导引定向制导机制,引导飞行器沿指定航向飞向目标;在此基础上,提出了基于侧向加速度补偿的定向定姿机动策略,主动产生侧向加速度以实现飞行器动态平衡,保证面对称飞行器能够同时满足并维持定向能载荷正常工作所需要的航向和倾斜角约束,确保定向能载荷拥有充足的照射时间。仿真结果表明,研究提出的基于侧向加速度补偿的机动制导策略,能够满足定向能载荷约束下面对称飞行器的定向定姿制导任务要求,对支撑机载定向能武器的实际运用具有一定的参考价值。Airborne directed energy weapons are one of the decisive factors to gain asymmetric advantages in future offensive and defensive confrontations.To address the problem of multiple constraints of the position,flight direction and bank attitude of the plane symmetrical aircraft under the requirement of effective damage to the target caused by directed energy load,a multiple constraint maneuvering guidance strategy with specified direction and attitude is proposed based on lateral acceleration compensation.The mission scenario of airborne directed energy loads attacking ground targets is described,and the maneuvering laws as well as constraints of position,flight direction and bank attitude of the plane symmetrical aircraft restricted by directed energy load are revealed.Based on the kinematic model and the multiple constraints such as position,specified direction and attitude of plane symmetrical aircrafts,the maneuvering guidance strategy of“virtual guidance-specified attitude attack”is designed to coordinate the imposed time and conditions of each constraint,which helps avoid the problem of command solution difficulty caused by excessive constraints.The coupling correlation characteristics existing in all constraints are analyzed,and a specified direction virtual guidance mechanism is proposed to guide the aircraft to the target on the specified course.On this basis,a specified direction and attitude maneuvering strategy with lateral acceleration compensation is proposed to actively generate the lateral acceleration for realizing dynamic balance of the aircraft,which can ensure that the plane symmetrical aircraft can simultaneously satisfy and maintain the heading angle as well as the bank angle constraints required for the normal operation of the directed energy load,and the directed energy load has sufficient rradiation time.The simulation results indicate that the proposed maneuvering guidance strategy based on lateral acceleration com-pensation can meet the requirements of the guidance mission with specifi
