摘要为了提高机器人灵巧手基关节的轨迹跟踪精度，提出了包含同步误差和位置误差反馈项及平滑鲁棒非线性反馈补偿项的交叉耦合同步控制策略，并建立了手指动力学模型．基于李亚普诺夫稳定性理论证明了所提出的控制策略能够使同步误差和位置误差均收敛到0，并且保证了系统的渐近稳定性．与传统非同步控制的PD加摩擦力补偿算法和轨迹跟踪控制算法进行比较，实验结果验证了所提出控制策略的有效性．

Abstract：A synchronized cross-coupled control approach is presented to improve trajectory tracking accuracy for base joint of dexterous robot hand, including feedbacks of synchronous errors and position errors, and a smooth robust nonlinear feedback compensator. The dynamics model of the robot is also established. According to Lyapunov stability analysis, it is proved that the proposed method can guarantee both synchronization and position errors converge to zero and the system is asymptotically stable. The proposed control strategy is compared with conventional non-synchronized PD friction compensation and trajectory tracking control, and experimental results demonstrate its validity.

Key words： dexterous robot hand cross-coupled control synchronized control trajectory tracking
