摘要:

具有运动学不确定性的机器人自适应控制中最具挑战性的问题之一是要求回归形式的雅可比矩阵求逆。这种要求是不可避免的情况下,控制的并联机器人,其动力学方程直接写在任务空间。基于雅可比矩阵的回归形式,设计了一种并联机器人自适应控制器,保证了机器人轨迹的渐近跟踪。其主要思想是将雅可比矩阵的行列式与伴随矩阵分离,并组织新的回归量形式。对2-DOF R \underline{P} R和3-DOF冗余度索驱动机器人的仿真和实验结果表明,所提出的方法具有良好的性能。

英文摘要:

One of the most challenging issues in adaptive control of robot manipulators with kinematic uncertainties is requirement of the inverse of Jacobian matrix in regressor form. This requirement is inevitable in the case of the control of parallel robots, whose dynamic equations are written directly in the task space. In this paper, an adaptive controller is designed for parallel robots based on representation of Jacobian matrix in regressor form, such that asymptotic trajectory tracking is ensured. The main idea is separation of determinant and adjugate of Jacobian matrix and then organize new regressor forms. Simulation and experimental results on a 2--DOF R\underline{P}R and 3--DOF redundant cable driven robot, verify promising performance of the proposed methods.
