| | Presents a new adaptive control scheme for the robot.It compensates for the effects of coupling,parameter uncertainty and nonlinearity and ensures the convergence of the whole system as well.The controller is divided into two categories. Conventional control which ensures that the robot path trajectory will be in the neighborhood of the desired trajectory; adaptive control which eleminates the servo-errors and forces the trajectory to approach the desired trajectory.The computer simulation results are... | | 针对机器人的动态模型,提出一种自适应控制方法,它不但可以消除参数不确定和各关节之间的耦合作用,而且也保证了整个系统的收敛性。整个控制器分为两部分:一是常规控制,用于将机器人的实际运动轨迹控制在期望轨迹的某一邻域、一是自适应控制,用于清除伺误差,并强迫实际运动以渐近方式趋于期望轨迹。计算机仿真的结果用来讨论了在不同环境条件下的系统性能。 | | 文摘来源 | | The singularity problem is inherent in controlling articulated robot manipulators. In this paper, we de-termine the required joint motion of the end effectors by evaluating their accuracy and feasibility. The ro-bust inversion of singularity of the Jacobian matrix provides a motion approaching to the desired cartesiantrajectory at or in the neighborhood of singular points for the end effector, even when the inversekinematic solution represented by Jacobian matric inversion or pscudo inversion is infea... | | 奇异性问题在用关节联接的机器人操作器的控制中是一个固有的问题.本文中.我们从考虑关节运动的精确性和可行性出发来确定操作器末端器所需运动时的关节运动.这种确定关节运动的方法称为具有奇异鲁棒逆的逆运动学解.之所以说它具有鲁棒性,是因为它在奇异点也能提供连续解.即使雅可比矩阵的逆或广义逆表示的道运动学解在奇异点或其周围不可行时,雅可比矩阵的奇异鲁棒逆也能为操作器末端器提供一个期望坐标轨迹的近似运动.对奇异鲁棒逆的特性与广义逆的特性进行了比较.并考虑了可行性的标量加权值. | | 文摘来源 | | The topological analysis of the CNN (Cellular Neural Network) given by L.O.Chua is presented in this paper. The topological construction of the neighborhood system for the one-cell and 8-connections cas be generalized to that of the one-cell and d-connections (d= 3,4,5,6,7). Therefore, a lot of different topologies of CNN will be created, at the same time offers many selected schedules of the VLSI implementations of CNN, and stimulates the developing work of the ASIC for CNN. | | 本文对于L.O.Chua(蔡少棠)所提出的细胞神经网络(CNN)的拓扑结构进行了较详细的分析,将单细胞-8连接的近邻系统的拓扑结构推广到单细胞-d连接d=3)4,5,6,7)的情况.这样,一大批具有不同拓扑结构形式的CNN将随之出现,将为CNN的VLSI实现提供多种可供选用的方案,并将有力地推动新型结构的CNN专用电路的研制工作. | | 文摘来源 | |   | | << 更多相关文摘 |
