The application discloses a kind of multi-constraint terminal velocity optimal midcourse guidance methods suitable for long-range glider, including the following steps: launch platform plans the midcourse guidance trajectory of terminal velocity optimization;Launch platform extracts track point from midcourse guidance trajectory, and passes to aircraft;Aircraft generates midcourse guidance instruction according to received track point;According to midcourse guidance instruction, the flight process of aircraft is controlled.The multi-constraint terminal velocity optimal midcourse guidance method suitable for long-range glider provided by the application can meet time, angle and other terminal constraints simultaneously, and ensures that the kinetic energy loss of midcourse guidance section is minimum, and the maximum gliding distance of aircraft is enhanced.

An intelligent CTU rack and an anti-shake control method and apparatus therefor, and a terminal. The method comprises: acquiring a goods placement instruction for controlling the operation of an intelligent CTU rack, and on the basis of the goods placement instruction, controlling a retractable structure to clamp a rack body, wherein the goods placement instruction comprises an initial velocity, a terminal velocity and the maximum acceleration for the operation of the intelligent CTU rack; processing the initial velocity, the terminal velocity and the maximum acceleration, so as to obtain a velocity curve; and on the basis of the velocity curve, controlling the operation speed and operation time of the extension of a fork in the rack body, so as to obtain a goods release instruction when the fork in the rack body is extended in place. In the method, the retractable structure is first controlled, on the basis of the goods placement instruction, to clamp the rack body, so as to stabilize the rack body of the intelligent CTU rack, and then the operation speed and operation time of the extension of the fork in the rack body are controlled by means of the velocity curve, such that the fork in the rack body is extended in place, and thus impact forces generated during the extension and retraction of the fork in the intelligent CTU rack are both reduced.
