Distributed spacecraft solar panel vibration control method considering adjacent control force

Abstract

The invention discloses a distributed spacecraft solar panel vibration control method considering adjacent control force, relates to the field of aerospace control systems, and solves the problems that when an existing centralized control system carries out vibration suppression on a large flexible component, the vibration suppression time is long due to the fact that a single controller cannot meet the control requirement. According to the method, the solar panel is divided into sub-modules according to the mounting positions of the actuator sensors on the solar panel, the actuator sensor of each sub-module and a control circuit of the actuator sensor form a control node, a vibration equation of the sub-module is established, and according to the vibration equation, the vibration of the sub-module is calculated. The influence of the installation positions of actuators and sensors on the control effect is considered, the coupling relation between the sub-modules is analyzed, the coupling influence of output force of adjacent control nodes is considered, and a distributed self-adaptive controller is provided. According to the invention, the vibration suppression time is shorter, and the anti-interference capability is effectively improved.

Description

technical field [0001] The invention relates to the field of aerospace control systems, in particular to a method for controlling the vibration of solar panels of distributed spacecraft considering adjacent control forces. Background technique [0002] In order to ensure the stability of the spacecraft’s in-orbit operating environment and effectively suppress the vibration of the large flexible parts of the spacecraft caused by the external environment and its own attitude adjustment, the designed control systems are divided into two categories, one is the traditional centralized control system, and the other is a distributed control system. In the traditional centralized control system, when performing vibration suppression control, all the vibration information of the sailboard is collected by the sensor as the input of the system, calculated by the on-board computer, and output the control rate. This centralized control system has a certain control effect, but because th...
