摘要

研究了存在不确定性条件下机器人机械臂的基于图像的视觉伺服。该控制技术由预补偿项、比例导数控制器(PD)和滑模控制器(SMC)组成,以实现快速、准确和鲁棒的运动。利用李雅普诺夫方法保证了闭环系统的实际稳定性。仿真结果验证了该控制器在正常和不确定条件下的有效性。

Pre-Compensated Proportional Derivative Sliding Mode Controller Design for Image Based Visual Servoing
This study deals with image based visual servoing (IBVS) of robot manipulators in the presence of uncertainties. The proposed control technique is composed of a pre-compensated term, proportional-derivative (PD) controller and a sliding mode controller (SMC) to reach fast, accurate and robust motions. Practical stability of the closed-loop system is guaranteed by using Lyapunov method. Simulation results are used to demonstrate the effectiveness of the proposed controller in the normal and uncertain conditions.
