摘要：
For a flexible agile satellite, a method of angular acceleration trajectory planning is proposed to suppress the vibration after maneuvering. Under the condition of frequency uncertainty, the amplitude of residual vibration can be suppressed into a certain range by the designed angular acceleration trajectory. On the analogy of the expression of the residual vibration excited by the cosine function with different power, an angular acceleration trajectory with multiple unknown parameters is designed. These unknown parameters are solved by adding constraints on residual vibration, thus improving the shortcoming that the cosine function will increase more maneuvering time to suppress vibrations with low frequency. Compared with the input shaping method, the angular acceleration trajectory designed by this method has a smoother trajectory, shorter maneuvering time and better suppression ability to high frequency vibration. © 2016, Editorial Dept. of JA.
