چکیده
Solar panel is an important structure of the spacecraft, SADA (Solar Array Drive Assembly is often used as the drive organ to realize the step-skipped gesture adjustment. Firstly, the dis turbance mechanism impact, which was produced from working SADA, to the electro-mechan ism and payload coupling has been taken into account, and the dead, rigid and flexible load S ADA disturbance model was established and validated through simulation and experimental measuring. Secondly, implemented the experimental check, calibration and correction to the mathematical model. Finally, the definition of electrical rigidity was proposed to analyze the disturbance mechanism of SADA, and verified its existence through simulation and testing.

متن کاملOptimal Reconfiguration of Solar Photovoltaic Arrays Using a Fast Parallelized Particle Swarm Optimization in Confront of Partial Shading
Partial shading reduces the power output of solar modules, generates several peak points in P-V and I-V curves and shortens the expected life cycle of inverters and solar panels. Electrical array reconfiguration of PV arrays that is based on changing the electrical connections with switching devices, can be used as a practical solution to prevent such problems. Valuable studies have been perfor...
