Embodiment Construction

[0048] The present invention will now be further described in conjunction with the embodiments and accompanying drawings:

[0049] The present invention is based on robust H ∞ Control and L 1 Adaptive control, active flutter suppression for missile bodies. Firstly, the projectile body is simplified into a free beam structure at both ends, and the aeroelastic model of the projectile body is established; then the projectile body model is decoupled into a rigid body subsystem and an elastic body subsystem, and H is used for the rigid body subsystem. ∞ control, using L for the elastomer subsystem part 1 The adaptive control is reorganized into an active vibration reduction controller; the feasibility of the method is verified by simulation analysis of the flutter suppression effect of the combined controller on the projectile.

[0050] The present invention includes the following steps:

[0051]Step 1: Build the projectile dynamics model

[0052] The invention derives the add...

Abstract

The invention relates to a combined controller design method for projectile flutter suppression. The projectile model is decoupled into a rigid body subsystem and an elastic subsystem, and H∞ control is used for the rigid body subsystem. The L1 adaptive algorithm is controlled, and then reorganized into an active vibration reduction controller to suppress the flutter of the projectile.

Description

technical field [0001] The invention belongs to an active flutter suppression method for a missile, which simplifies the missile into a free beam structure at both ends to establish a missile body model, proposes to decouple the model into a rigid body and an elastic body, design controllers separately, and then combine them into a flutter suppressor for the missile. Compared with the traditional method, the vibration suppression effect is much improved. Background technique [0002] Under the strong impetus of the current world's new military revolution, as an important means to achieve precision strikes, missile weapons have been widely used in several typical high-tech wars in recent years, and have become an important part of modern information warfare. As one of the main weapons of war, all military powers have clearly listed the development of missile weapons in their national military key development strategies. [0003] In order to increase the flight speed and incr...
