Design method of combined controller for missile body flutter suppression

Abstract

The invention relates to a design method of a combined controller for missile body flutter suppression. A missile body model is decoupled into a rigid body subsystem and an elastic body subsystem; forthe rigid body subsystem, H-infinity control is used; for the elastic body subsystem, L1 self-adaptive algorithm control is designed; and then the H-infinity control and the L1 self-adaptive algorithm control are recombined into an active flutter reduction controller, and the active flutter reduction controller conducts flutter suppression on a missile body.

Description

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