| 1 | Vibration suppression of a large flexible spacecraft for on-orbit operation显示文摘Flexible appendages, such as solar panels, communication antennas and other large structures, are mounted on the base of a space robot and target satellite. The vibration of the flexible structure is excited by operations of a space manipulator. It is very challenging to control the vibration of large flexible appendages for on-orbit operation and, especially when the manipulator operates a non-cooperative target with unknown structural parameters and vibration information. In this study, a hybrid control method is proposed based on wave-based control and PD control methods to control the motion of a manipulator while suppressing the vibration of appendages. First, the rigid-flexible coupled dynamic model of a compounded system is established.This is followed by designing a hybrid control strategy combining wave-based control and PD control for restto-rest maneuvers based on the characteristics of the compounded system. Finally, the simulation of a 3D compounded system is provided to verify the effectiveness of the presented approach. The simulation results indicate that the space robot can successfully berth the target while suppressing the vibrations of the structure. | Deshan MENG Houde LIU Yanan LI Wenfu XU Bin LIANG | 2017 | Science China(Information Sciences)2017，60，5： | 6 |
| 2 | Bioinspired Spiral Soft Pneumatic Actuator and Its Characterization显示文摘Soft robots have unique advantages over traditional rigid robots and have broad application prospects in many fields.To expand their bioinspired applications,we propose a novel Soft Pneumatic Actuator(SPA)associated with spiral configuration inspired by the structure and unwinding motion of the seahorse tail.Diff erent from bending motion of common soft actuators,the spiral SPA can generate unwinding motion as input air pressure increases.First,to explore the eff ect of diff erent initial spiral types on unwinding performance,three typical spiral SPAs are designed and simulated while keeping the outside arc of actuator body constant.Second,a static model of the spiral SPA is established by combining the hyperelastic material model,geometric relationships,and virtual work principle.To improve model accuracy,two geometric correction parameters are employed and their physical significance is analyzed by finite element simulations.Third,a prototype of the logarithmic spiral SPA(Log_spiral SPA)is fabricated and a Fiber Bragg Grating(FBG)sensor array is designed to detect and reconstruct unwinding shapes of the prototype.Finally,the unwinding performance,static model and output force capability of the prototype are tested and verified.Furthermore,we discuss prospects for this novel spiral SPA and test its practical applications in inchworm-like motion,assisting finger rehabilitation and object capture. | Zhiyuan Zhang Xueqian Wang Deshan Meng Bin Liang | 2021 | Journal of Bionic Engineering2021，18，5： | 1 |

| 4 | Cooperative planning ofmulti-agent systems based on task-oriented knowledge fusion with graph neural networks显示文摘Cooperative planning is one of the critical problems in the field of multi-agent system gaming.This work focuses on cooperative planning when each agent has only a local observation range and local communication.We propose a novel cooperative planning architecture that combines a graph neural network with a task-oriented knowledge fusion sampling method.Two main contributions of this paper are based on the comparisons with previous work:(1)we realize feasible and dynamic adjacent information fusion using GraphSAGE(i.e.,Graph SAmple and aggreGatE),which is the first time this method has been used to deal with the cooperative planning problem,and(2)a task-oriented sampling method is proposed to aggregate the available knowledge from a particular orientation,to obtain an effective and stable training process in our model.Experimental results demonstrate the good performance of our proposed method. | Hanqi DAI Weining LU Xianglong LI Jun YANG Deshan MENG Yanze LIU Bin LIANG | 2022 | Frontiers of Information Technology & Electronic Engineering2022，23，7： | 0 |
