摘要

提出了一种具有简化非线性反馈的精确线性化方案的动态模型。为了在机器人系统中实现该模型,需要选择输出函数,使其满足总惯性矩阵的特殊分解。利用虚拟机器人的概念实现了模型的制定和实现问题的解决。文中给出了两个说明性的例子,一个是斯坦福臂,另一个是PUMA型机器人。讨论了基于新模型的机器人优化物理设计和控制系统设计。>

Dynamic modeling and control by utilizing an imaginary robot model
A dynamic model that represents an exact linearization scheme with a simplified nonlinear feedback is presented. To realize this model for robotic systems, the output functions should be chosen so that a special decomposition of the total inertial matrix is satisfied. The concept of an imaginary robot is utilized to achieve the formulation and to solve the realization problem. Two illustrative examples are given in the paper, one for the Stanford arm and the other for a PUMA type of robot. An optimal robotic physical design and a control system design based on the new model are also discussed. >
