摘　　要：以某新型反坦克导弹为研究对象,分析了转弯过程中弹体滚转对偏航通道的马格努斯效应,探讨了在复合联动舵机的快速响应条件下,弹体快速准确完成初始段转弯、全方位飞行的垂直发射的理论与工程方法。建立了导弹的全方位发射制导控制模型,并设计了基于极小值原理的弹体最优滚转角控制律;考虑弹体与舵机约束,提出了一种适用于工程实际的弹体滚转角控制函数优化模型。仿真结果表明,在保证导弹姿态稳定所需时间基础上,弹体能以较快的速度按照所设计的滚转角控制律完成全方位滚转,实现了导弹在空中自主完成全方位发射所需的弹体滚转。A new type of anti-tank missile is studied,and the Magnus effect of roll-to-yaw channel in the process of turning is analyzed. Under the condition of rapid response of composite linkage servo,the theory and engineering method of vertical launching of the missile body quickly and accurately complete initial section turning and all-round flight are discussed. The missile＇s omnidirectional launch guidance and control model is established,and the optimal roll angle control law of the missile based on minimum principle is designed. Considering the constraints of the missile body and the steering gear,an optimal model of the roll angle control function suitable for engineering practice is proposed. Simulation results show that,based on the time required to stabilize the attitude of the missile,the missile body can roll in all directions at a faster speed in accordance with the designed roll angle control law,which realizes the missile body roll in the air to complete all-round launch.
