Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, refer to the attached figure 1 -3 The present invention is described further.

[0039] The invented roll angle instruction online planning method comprises the following steps:

[0040] Step 1: Solve the required overload for altitude stability control

[0041] The highly stable control adopts the classic control theory PD control structure, and its structure diagram is as follows: image 3 As shown, the stable altitude needs to use the overload command

[0042] no Hc =k vy [k H (H c -H)-V y ] (8)

[0043] In the formula, H c Indicates the height command of the target flight, H is the current height of the target, V y is the component of the velocity of the target on the y-axis of the emission system, k H 、kvy is the height control parameter of the target, n Hc The overload command in the y-axis direction of the launch system required for altitude maintenance.

Abstract

The invention provides a high-stability control method for continuous high-overload maneuver of a supersonic high-maneuver target, which is a high-stability control method for controlling the target of a pitching and rolling channel only by an elevator and an aileron in the process of continuous high-overload maneuver in a horizontal plane. According to the method, firstly, overload nHc in the y direction of a transmitting system required by target height stability control is analyzed, under the condition that a preset overload instruction nyc is non-adjustable, in order to ensure that the height is kept stable in the horizontal maneuvering process, an online roll angle instruction planning algorithm is designed, and according to the algorithm, a roll angle instruction is planned in real time, so that the target height stability is guaranteed. Therefore, the component of the predetermined overload instruction nyc in the y direction of the launch system is equal to the highly stable required overload nHc, and the highly stable target in the flying process of the horizontal maneuver process is ensured. Flight test results prove the effectiveness of the method.

Description

technical field [0001] The invention relates to a method for controlling the height stability of a supersonic large maneuvering target during continuous large overload maneuvering, in particular to a method without rudders, only relying on elevators and ailerons to control the two channels of pitch and roll, so as to realize the continuous large overload maneuvering of the target altitude stability control. Background technique [0002] The target is a kind of aircraft that can simulate combat aircraft and incoming missiles, and provides air targets for the development, finalization and identification tests of surface-to-air missiles and air-to-air missiles, as well as actual combat training of troops. The performance of a country's targets is the touchstone for evaluating the strength of a country's weapons and equipment. Data show that the ceiling of the American F22 fighter jet can reach 18km, the maximum flight Mach number is 2.0Ma, the overload of stable hovering is no...
