Problems solved by technology

[0002] Traditional optoelectronic stabilized platforms generally adopt direct stabilization or strapdown stabilization methods. For high-speed rotating motion carriers, affected by the performance of inertial devices, the measurement range and measurement bandwidth cannot meet the requirements of stable high-speed rotating platforms. The control method of traditional stabilized platforms Cannot effectively isolate carrier movement

Abstract

The invention belongs to the technical field of a photoelectric stabilization tracking platform, and particularly relates to a sight line stabilization control method for a high-speed rotating platform. The method comprises the following steps: step one: coordinate systems, including a pedestal coordinate system, an external frame coordinate system and an internal frame coordinate system, are established; step two: a framework kinetics relation is established on the basis of the coordinate systems established in the step one; and step three: bi-stable loop cascade control is performed on the high-speed rotating platform on the basis of the kinetics relation established in the step two. The sight line stabilization method of the high-speed rotating platform is divided into two types of control loops of rotating stabilization and direct sight line stabilization. Each loop adopts independent controller design so that influence of high-speed rotation on sight line stabilization is separated, stabilization accuracy in sight axis is enhanced, a defect of poor stabilization accuracy of an existing photoelectric stabilization platform in the high-speed rotating state is overcome, and problems of high stability and high accuracy of the photoelectric platform, especially a staring type infrared seeker system, are solved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric stable tracking platforms, and in particular relates to a line-of-sight stabilization control method for a high-speed rotating platform. Background technique [0002] Traditional optoelectronic stabilized platforms generally adopt direct stabilization or strapdown stabilization methods. For high-speed rotating motion carriers, affected by the performance of inertial devices, the measurement range and measurement bandwidth cannot meet the requirements of stable high-speed rotating platforms. The control method of traditional stabilized platforms Cannot effectively isolate carrier movement. Contents of the invention [0003] The object of the present invention is to provide a line-of-sight stabilization control method for a high-speed rotating platform, specifically a double-stable ring method of rotation stabilization + line-of-sight stabilization, which divides the line-of-sight stabilizat...
