摘要

本文提出了一种基于比例导数(PD)控制概念的同步控制方案,并结合时滞估计(TDE)控制方案对闭式链式机械臂(CKCM)进行了同步控制。该方法采用同步技术、PD控制和TDE控制,保证了跟踪误差的全局渐近收敛,同时在存在不确定性的情况下强制所有活动关节以预定义的同步方式运动。通过2自由度平面CKCM机械臂的计算机仿真,对所提出的控制方法进行了性能评估,并对仿真结果进行了讨论。

An Advanced PD Controller for Robot Manipulators with Time-Delay Estimation
This paper proposed a Synchronization control scheme based on the the concept of Proportional Derivative (PD) control developed for in conjunction with the time-delay estimation (TDE) control scheme for the closed-kinematic chain manipulator (CKCM). By employing the synchronization technique, PD control and TDE control, the proposed method that ensures the global asymptotic convergence of tracking errors while forcing all active joints to move in a predefined synchronous manner in the presence of uncertainties. The performance of the proposed control is assessed by computer simulation on a 2 degrees-of-freedom (DOF) planar CKCM manipulator and simulation results are presented and discussed.
