Interference-resistant gesture control verification platform and interference-resistant gesture control verification method based on output feedback

Abstract

The invention relates to an interference-resistant gesture control verification platform and an interference-resistant gesture control verification method based on output feedback. The interference-resistant gesture control verification platform comprises a real-time simulation target machine, a gesture determining module, a gesture control module, a counteraction flywheel set, an experiment master control module, an interference simulator and a three-axis air bearing table. The real-time simulation target machine operates an aircraft gesture kinematic model. The gesture determining module performs filtering and resolving of gesture information which is output from the real-time simulation target machine. The gesture control module operates a gesture control algorithm and supplies a moment control instruction to the counteraction flywheel set. The counteraction flywheel set receives the moment control instruction and outputs a moment signal to the simulation target machine. The experiment master control module transmits a control method switching signal to the gesture control module, and an interference-resistant gesture control module operates a corresponding control algorithm according to the switching signal. The interference simulator simulates a vibration interference of a flexible component. The three-axis air bearing table simulates the kinematic environment of an aircraft in an outer space. According to the interference-resistant gesture control verification platform and the interference-resistant gesture control verification method, effectiveness of the interference-resistant gesture control verification method based on output feedback is verified.

Description

technical field [0001] The invention relates to an anti-jamming attitude control verification platform and verification method based on output feedback, belonging to the field of attitude control of spacecraft. Background technique [0002] With the continuous development of space technology and the continuous growth of aerospace needs, more and more spacecraft carry flexible mechanisms such as large parabolic antennas, solar panels, space manipulators, etc. These flexible mechanisms make the spacecraft more and more powerful , but at the same time it also brings a severe test to the attitude control of the spacecraft, especially when the control accuracy of the spacecraft is high, such as earth observation satellites, space telescopes, etc. Once this large flexibility and low damping structure encounters external interference, it will generate vibration, which will seriously affect the normal operation of the payload, resulting in performance degradation or failure.

[0003] The attitude control method verification platform has been widely used in the development of spacecraft. 502 domestic aerospace institutes, 812 aerospace institutes, and Harbin Institute of Technology, Tsinghua University, Beihang University and other universities have developed attitude control method verification platforms. Existing verification devices for attitude control methods are usually developed for a specific type of spacecraft, and some are only for a specific space mission. They are built to verify a specific method, ignoring the influence of interference such as vibration of flexible components, and cannot be used for Research on Multiple Anti-jamming Attitude Control Methods for Vibration Disturbance of Flexible Parts

The document "Real-time Simulation of Micro-satellite Attitude Control Based on Air-floor Platform" published in "Journal of Beijing University of Aeronautics and Astronautics" Volume 36 No. 7 in July 2010 established a semi-physical simulation experiment platform for the attitude control of a single rigid body micro-satellite A real-time simulation study was carried out. The control method is the traditional PID control method. This method cannot effectively offset the interference caused by the vibration of flexible components. At the same time, the test platform cannot complete the test and analysis of various anti-interference control methods.
