Summary: | The invention discloses a nonlinear optimal flight time control guidance method for intercepting a maneuvering target. The method comprises the following steps: establishing a nonlinear guidance model in an inertial system and converting the nonlinear guidance model into a relative virtual coordinate system; the basic form of constructing the guidance law is the sum of a zero-control miss distance control item and a relative flight path error control item; a zero-control miss distance control item meeting a given performance index is deduced on the basis of the optimal control principle, a relative flight path error control item is determined on the basis of an optimal relative flight path error kinetic equation in an arc length domain, and therefore a nonlinear optimal relative flight path control guidance law is obtained; and designing a future average speed prediction algorithm, and establishing a relation between the relative flight distance and the flight time so as to realize flight time control.
