Active section self-adaptive longitudinal guidance method based on view acceleration measurement

Abstract

Provided is an active section self-adaptive longitudinal guidance method based on view acceleration measurement. According to an axial view velocity increment cumulative sum, a standard procedure angle is automatically adapted, and it is guaranteed that flying can still be achieved according to a procedure track with high precision under high power deviation. An axial view velocity increment cumulative sum-pitching procedure angle data list is bound in a data mode, a carrier can generate a procedure command just relaying on view acceleration measurement, and other input conditions and complex calculation are not needed; a guidance command changes according to an actual power level in a self-adaptive mode, auxiliary guidance is not needed, and therefore the contradiction of guidance distribution is avoided. In actual use, reliable measures can be carried out on input quantity and output quantity, and it is guaranteed that the method is feasible in engineering application.

Description

technical field [0001] The invention relates to a guidance method, in particular to an adaptive longitudinal guidance method for active segment procedure flight. Background technique [0002] The characteristics of the flight of the carrier are to take off vertically, and then turn and fly according to the pre-calculated flight program. The guidance command is usually given in the form of a sequence of pitch program angles that vary with time. For ease of use, the guidance parameters are time-dependent variables The pitch program angle interpolation table or the pitch program angle polynomial fitting coefficient table with time as the independent variable. Arrow flight software performs linear interpolation calculation or polynomial calculation based on flight timing, and can issue guidance program instructions in real time. This method does not rely on measuring equipment, and the calculation is simple and reliable. If the flight conditions such as atmospheric state, engi...
