Abstract

The invention discloses an aircraft gliding deceleration control method. The method comprises steps that whether deceleration control is needed is determined according to a difference value of an instruction speed Vcx provided by a guidance system and a motion speed Vd of an aircraft relative to the Earth acquired by a navigation system; if yes, a required basic attack angle alpha0 is acquired through calculation; a dissipation speed deltaV is acquired through calculation; a required deceleration attack angle alphan is acquired through calculation; an additional guidance force Fzc<V> for deceleration control is acquired through calculation; deceleration control on the aircraft is carried out according to the additional guidance force for deceleration control acquired through calculation. Through the method, precise speed control on the aircraft can be realized.

Description

technical field [0001] The invention relates to the technical field of hypersonic vehicle guidance, in particular to a control method for gliding deceleration of the vehicle. Background technique [0002] For the lift aircraft, because it mainly relies on aerodynamic flight, under the influence of uncertain factors and interference conditions, the velocity dispersion of the aircraft at the end of the flight is large, which is unfavorable to the subsequent flight. In order to constrain the velocity distribution of the terminal point, it is necessary to Strict speed control is carried out so that the speed tends to be consistent under disturbance conditions. [0003] However, an effective and high-precision aircraft glide deceleration control method has not yet been provided in the prior art, so this problem needs to be solved urgently. Contents of the invention [0004] In view of this, the present invention provides a method for controlling the gliding deceleration of the...
