A Structural Filter Used to Eliminate the Effect of Air-to-Air Missile Body Vibration

Abstract

The invention relates to the control problem of missile elastic body, in particular to a structural filter for eliminating elastic vibration of air-to-air missile body. It consists of an input terminal Vin, an output terminal Vout, an operational amplifier and a bridge resistance-capacitance network. The structural filter of the invention meets the application requirements of a certain type of missile. In addition to meeting the required amplitude-frequency and phase-frequency characteristics, it also has the advantages of novel design ideas, small size, compact structure and easy adjustment.

Description

A Structural Filter Used to Eliminate the Effect of Air-to-Air Missile Body Vibration technical field The invention relates to the control problem of missile elastic body, in particular to a structural filter for eliminating elastic vibration of air-to-air missile body. Background technique The main function of the structural filter is to filter out the individual frequency components in the pitch and yaw control loops, so as to eliminate the adverse effects of the elastic vibration of the missile body on the missile during autonomous flight. There are many mature technologies for filter circuits, such as Butterworth filters, Chebyshev filters, etc., but these mature filters cannot meet the requirements of a certain type of air-to-air missile in my country due to their single filtering characteristics. The design of the instrument is limited by the calculation speed of the flight control computer, and in consideration of minimizing the time occupied by the flight control co...
