| 1 | 挠性航天器退步自适应姿态机动及主动振动控制显示文摘针对带有分布式压电陶瓷执行机构的挠性航天器姿态机动与主动振动控制问题,提出了一种退步直接自适应一体化控制方法.首先,建立了挠性航天器姿态机动与主动振动控制的模型,并分析了动力学子系统的近似严格正实性;然后,采用退步直接自适应控制方法,设计了挠性航天器的姿态机动主动振动控制器,并证明了控制闭环系统的稳定性;最后,进行了不同仿真条件下的数学仿真验证.理论分析与数学仿真结果表明,该控制方法不依赖航天器参数,对系统参数不确定性具有强鲁棒性,能有效抑制挠性附件的振动,对挠性航天器的控制是有效的. | 刘敏 杨军 李学林 徐世杰 | 2015 | 空间控制技术与应用2015，41，1： | 4 |
| 2 | Singular formalism and admissible control of spacecraft with rotating flexible solar array显示文摘This paper is concerned with the attitude control of a three-axis-stabilized spacecraft which consists of a central rigid body and a flexible sun-tracking solar array driven by a solar array drive assembly. Based on the linearization of the dynamics of the spacecraft and the modal identities about the flexible and rigid coupling matrices,the spacecraft attitude dynamics is reduced to a formally singular system with periodically varying parameters,which is quite different from a spacecraft with fixed appendages. In the framework of the singular control theory,the regularity and impulse-freeness of the singular system is analyzed and then admissible attitude controllers are designed by Lyapunov's method. To improve the robustness against system uncertainties,an H1optimal control is designed by optimizing the H1norm of the system transfer function matrix.Comparative numerical experiments are performed to verify the theoretical results. | Lu Dongning Liu Yiwu | 2014 | Chinese Journal of Aeronautics2014，27，1： | 3 |
| 3 | Impact vibration reduction for flexible manipulators via controllable local degrees of freedom显示文摘When performing operation tasks,the interaction between a flexible manipulator and a grasped object usually results in an impact.In this paper,a new way is suggested to alleviate impact vibration of a flexible manipulator via its structural characteristic when capturing a moving object.Controllable local degrees of freedom are introduced to the topological structure of the flexible manipulator,and used as an effective tool to combat impact vibration through dynamic coupling.A corresponding method is put forward to reduce impact vibration responses of the flexible manipulator via the controllable local degrees of freedom.By planning motion of the controllable local degrees of freedom,appropriate control force can be constructed to increase the modal damping and stiffness and eliminate the exciting force simultaneously,thereby reducing impact vibration responses of the flexible manipulator.Simulations are conducted and results are shown to prove the presented method. | Bian Yushu Gao Zhihui Deng Yuchun | 2013 | Chinese Journal of Aeronautics2013，26，5： | 1 |
| 4 | Extensions in adaptive model tracking with mitigated passivity conditions显示文摘Feasibility of nonlinear and adaptive control methodologies in multivariable linear timeinvariant systems with state space realization {A, B, C} has apparently been limited by the standard strict passivity (or positive realness) conditions that imply that the product CB must be positive definite symmetric. More recently the symmetry condition has been mitigated, requiring instead that the not necessarily symmetric matrix CB be diagonalizable and with positive real eigenvalues. However, although the mitigated conditions are useful in proving pure stabilizability with Adaptive Controllers, the Model Tracking question has remained open and counterexamples seem to demonstrate total divergence of standard model reference adaptive controllers when the regular passivity conditions are not fully satisfied. Therefore, this paper further extends the previous results, showing that the new passivity conditions do guarantee stability with adaptive model tracking. Examples show how the new conditions solve the case of flexible structures with unknown parameters when perfect collocation is not possible. Also, the so-called counterexamples become simple, well-behaved, examples. | Itzhak BARKANA | 2013 | Chinese Journal of Aeronautics2013，26，1： | 1 |
