一引言制导和控制一个飞行运动体(飞行器),本质上就是测量位置,决定航迹误差和控制航迹的校正等问题。这几个功能通常分别叫做导航、制导、操纵和控制。通常,这四种功能分别由单独的设备完成。其中,所谓制导系统指的是保证飞行器(如导弹)自动地导向目标的一些设备(包括硬设备和软设备)的组合。 I. INTRODUCTION Guidance and control of a flying body (aircraft) is essentially a measurement of the position, the determination of the trajectory error and control of trajectory correction and other issues. These functions are usually called navigation, guidance, manipulation and control. Often, these four functions are performed by separate devices. The so-called guidance system refers to a combination of some devices (including hard devices and soft devices) that ensure that an aircraft (such as a missile) automatically leads to a target.
