Embodiment Construction

[0036] A predmined flight technology applied to short-range ultrasound cruise:

[0037] (1) The inner ring control parameter design is performed according to the classic frequency domain analysis.

[0038] The inner ring control command is as follows:

[0039] δ z = K p (Α-α) c + K d · Ω z

[0040] Among them, K p K d It is necessary to design a control coefficient in this link.

[0041] (2) Generate an outer ring guide command, the way is as follows:

[0042]

[0043] Among them, you need to be in this link to K pθ K ph The two coefficients perform value, the height change value is much larger than the value of the local ballistic inclination, so k when adjusting parameters pθ Generally, far greater than K ph , You can take the initial 600 times the proportional relationship.

[0044] (2A) You can remove the height, only adjust K pθ After the consecutive step, the level cruise is reached, and the height link is added to achieve a high cruise.

[0045] (3) Combine the outer rin...

Abstract

The invention relates to a ground sweeping flight technology applied to a short-range supersonic cruising bomb, which inherits and optimizes a fixed-height flight technology applied to the short-range supersonic cruising bomb, ensures the stability of a flight attitude through an inner ring, generates a guide instruction of fixed-height flight through an outer ring, and improves the flight speed of the short-range supersonic cruising bomb. The inner ring controls the aircraft to track the guide instruction of the outer ring so as to achieve the purpose of fixed-height flight. Wherein the proportionality coefficient before the height item of the outer ring has certain adaptability to the height difference, the smaller the height difference is, the larger the coefficient is, and the cruise height error can be reduced to a large extent. When sweeping cruise at the height of 30 m is carried out, the cruise height error can be reduced to about + / -3 m from about + / -22 m (the fixed-height error of a fixed-height flight technology applied to a short-range supersonic cruise missile) under the limit pulling deviation condition, and therefore the method can be applied to sea sweeping cruise or sweeping cruise of the supersonic cruise missile within a short time.

Description

Technical field [0001] The present invention is applied to the radioped flying technology of the proximal ultrasonic cruise bullet, which is the field of aircraft attitude control, involving the longitudinal channel motion model and the posture control circuit of the aircraft. Background technique [0002] Due to the large low-altitude atmospheric density, when the low-altitude ultrasonic speed cruise, there is a need to overcome the pneumatic resistance with a large thrust, so it is generally used to perform long-distance predation or shooting. With the development of defensive weapons and detection methods, traditional oral cruise bombs and some ultrasound cruise bombs are easily intercepted. In order to better achieve the out-of-abundance of conventional ultrasound cruise bullets, the ballistic cruise has received more and more attention. It is one of the ways to reduce the ballistic, and the ballistic is almost excited in the late paragraph. Ultrasound and prednated or predfo...
