Frame control and integrative vibration isolation-based quadratic stabilization system of stratosphere airship

Abstract

The invention relates to a frame control and integrative vibration isolation-based quadratic stabilization system of a stratosphere airship, which comprises an active-passive integrative vibration isolator, a horizontal stabilized platform, a frame driving unit and a controller. The active-passive integrative vibration isolator is used for isolating the coupling of environmental disturbance and airship body movement, and a control driving command of the active-passive integrative vibration isolator is generated by the controller. The horizontal stabilized platform is used for providing a local horizontal plane for the frame driving unit and a subsequent actual load; and the horizontal stabilized platform feeds back an attitude angle to the controller, and then the controller adjusts the horizontal stabilized platform through an execution structure according to the deviation of the attitude angle so as to keep the horizontal stabilized platform to be parallel with the local horizontal plane. The controller controls the frame driving unit to a required pointing direction according to an object point, the current position of the airship, and corner information fed back by the frame driving unit. The invention provides a new quadratic stabilization platform system capable of meeting the requirements on a working environment with actual load, which has high control accuracy and good stability.

Description

Technical field [0001] The invention belongs to the field of aerospace control and relates to a secondary stabilization system for supporting a working platform of a stratospheric airship load. Background technique [0002] The major special project of high-resolution earth observation system is one of the 16 major special projects determined by the State Council’s "National Medium and Long-term Science and Technology Development Plan (2006-2020)". It is the top priority of my country’s scientific and technological development. An innovative large system. The high-resolution earth observation system classifies the stratospheric earth observation sub-system (referred to as the stratospheric sub-system) as the earth observation sub-system at the same level as space-based and aviation. The establishment of a stratospheric sub-system is of very important strategic significance. The development of stratospheric airship technology will also achieve the goal of extending my country's so...

Problems solved by technology

[0004] Judging from the characteristics of the airship hull itself and the current control level, the current method of directly controlling the huge hull of the stratospheric airship is far from meeting the basic requirements of the mission

At present, the research on airships at home and abroad generally focuses on the research on the airship platform, but there are no relevant proposals for related technologies such as secondary stable platforms.
