| 摘 要： | 研究在地球万有引力场和磁场中具有结构内阻尼的磁性刚体航天器在圆轨道上平面天平动的混沌行为及其控制。应用Melnikov方法建立了系统存在横截导宿环的条件。分别采用Poincare映射、功率谱和Lyapunov指数等数值方法对系统动力学行为进行识别。建立输出变量反馈线性比控制律及其局部线性化将混沌姿态运动控制为给定的不动点和周期运动。

| Abstract: | Chaotic attitude motion and its control of a magnetic rigid spacecraft in an arbitrary circular orbit round the earth are investigated. The dynamic model of the problem is established. The Melnikov analysis is carried out to present the condition of existing transversally heteroclinic cycles. The dynamic behaviors are identified by numerical means such as Poincare map, power spectrum and Lyapunov exponents. The input output feedback linearization control and its local linearization are respectively applied to control chaotic attitude motions to the given fixed point and periodic motion. |
