Abstract

The invention discloses a vibration self-inhibition solar panel substrate based on suspension rope tension measurement. One end of a panel substrate body is connected with a satellite body; a controller and a motor are arranged on the satellite body; one end of a convex frame is fixed at the middle part of the panel substrate body; one end of a suspension rope is fixed at a free end of the panel substrate body, and the other end of the suspension rope is connected with the motor; tensometers are connected in series on the suspension rope; the section in the middle of the suspension rope is in slip connection with the surface of the other end of the convex frame; and an accelerometer is arranged at the free end of the panel substrate body. When the panel substrate vibrates, the tension of the suspension rope is changed, the tensometers measure changes of the tension and transmit data to the controller, the vibration amplitude of the free end of the panel substrate is measured by the accelerometer, the data of the vibration amplitude is also transmitted to the controller, and the controller controls the motor according to a control algorithm to realize expansion and contraction of the suspension rope, thereby controlling the tension of the suspension rope. The invention adopts a suspension rope tension control scheme, and the control method not based on a mathematical model can effectively solve defects of control based on models.

Description

technical field [0001] The invention relates to a vibration self-inhibiting solar panel based on the measurement of suspension rope tension, and belongs to the technical field of vibration self-inhibiting solar panel. Background technique [0002] Solar panels are the main source of energy for satellites and a necessary component of satellites. Solar panels may vibrate under the influence of active loads and external disturbances during in-orbit operation. Due to the flexibility of the panels, the vibrations generated in the special space environment are not easy to attenuate, which affects the attitude stability and pointing accuracy of the satellite attitude control system. , may also lead to unstable vibration, thus affecting the normal operation of the satellite, so the vibration suppression of solar panels is very important. [0003] Chinese Patent No. ZL201520384925.0 (authorized announcement number CN204726686, authorized announcement date October 28, 2015) discloses...
