摘　　要：为了使近距格斗空空导弹在大离轴角发射时能快速地转向目标,需要研究快速转弯控制律。要求在给定的时间内使导弹由初始姿态转到所要求的姿态,并使导弹终端速度最大。应用最优控制理论,提出一种最佳快速转弯控制律,能在推力矢量控制下消除终端时刻垂直于初始视线方向上的速度分量。数字仿真表明,该控制律具有很好的性能,能使近距空空导弹在大离轴角发射时的截击能力得到提高。For quick truning to target of air-to-air missile (AAM) for short range dogfight in large off-boresight it is necessary to study the agile turn control law. The missile is demanded for turning to necessary attitude from initial one in given time and its final speed becomes maximum. Using the optimal control theory an optimal control law of agile turn is proposed enabling to eliminate velocity component in vertical director of initial sight under thrust vector control. The digital simulation based on this control law denotes that it possesses very well performance, and the interception ability of AAM for short range in launching of large off-boresight angle can be raised.\;
