【Abstract】 Considering the large flexibility in modern spacecraft and stepping motors are often used to drive the flexible appendages, in this paper, we discuss the active vibration suppression method with component synthesis. The corresponding mathematics model was built and the analysis of flexible vibration caused by different driving strategies of stepping motor and its influence on rigid attitude were done. A novel driving strategy using component synthesis method was proposed. Both numerical simulation and experiment validate this new method.更多还原
