卫星单轴太阳翼驱动系统建模与控制技术综述

In view of the complex problems currently faced by the satellite single-axis solar array drive system, the technological progress at home and abroad is comprehensively reviewed from multiple perspectives such as system modeling, control methods and ground verification. Firstly,the structure,operation principle and working mode of SADA are analyzed. Then,according to the load characteristics of SADA,the dynamic modeling methods of rigid and flexible solar wings are summarized,and the single control and composite control strategies are discussed for the difficulties of speed and angle control caused by nonlinearity,and various algorithms are compared and analyzed. Also,the microgravity simulation and load characteristic simulation methods adopted to improve the accuracy of SADA ground test verification are introduced. Finally,the research trend of future spacecraft SADA is summarized and prospected.
