固定配平攻角飞行器具有外形简单、控制通道少的优点,但其升力大小不可控,为实现精确制导,解决其带终端角度约束制导的问题,提出了一种含虚拟目标的滚转制导律设计方法。建立了含虚拟目标的滚转制导方程,给出了基本导引关系,并证明了该导引关系下设计的制导律能有效对飞行器落点与落角进行控制。同时,给出了虚拟目标详细设计方法,并通过数值仿真验证了该制导律的有效性。仿真结果表明,提出的含虚拟目标的滚转制导律设计方法具有较高的制导精度与落角精度,同时设计方法简单,便于工程应用。

Fixed?trim vehicle with attack angle has the characteristic of simple configuration and less control channels. Howev?er,as the magnitude of lift force is uncontrollable,an appropriate guidance law is needed to ensure the guidance accuracy.Thus,in order to solve the guidance problem with the control of terminal azimuth for fixed?trim vehicle,a rolling?guidance law with virtual tar?get was proposed. The rolling?guidance equation with virtual target was established. The basic guidance method was put forward, which is proved that the guidance law could accurately steer the vehicle and control the terminal azimuth effectively. The design method of virtual target was also given and the validity of rolling guidance was analyzed by simulation. The simulation result illus?trates that:the rolling?guidance law with virtual target in this paper not only has higher precision of guidance and terminal azimuth control,but also has the simple design,which is convenient for engineering application.
