Tracking Control of Flexible Arm Using Tendon Mechanism.

Control of Flexible Robot Arm

T h i s work is a computer simulation of the control of flexi ble robot arm. The dynamic equations for a single-link flexible robot arm have been derived rigorously. Th is arm has two degrees of freedom in rotation and one in translation so that the workspdce i s three-dimensional. The payload is simulated by attaching additional mass to the arm at a specified location. The governing equations ...

Control of a Lightweight Flexible Robotic Arm Using Sliding Modes

This paper presents a robust control scheme for flexible link robotic manipulators, which is based on considering the flexible mechanical structure as a system with slow (rigid) and fast (flexible) modes that can be controlled separately. The rigid dynamics is controlled by means of a robust sliding-mode approach with wellestablished stability properties while an LQR optimal design is adopted f...

Control of a Flexible Robot Arm

We model a exible robot arm supported at a prismatic joint so the length of (the relevant part of) the rod is variable | indeed, this variation in the length of the arm is taken to be the control action. The principal results are: exact controllability for the consideration of purely longitudinal vibrations (wave equation) and the existence of optimal controls in the more practically interestin...

Iterative Learning Control for Trajectory Tracking of Single-link Flexible Arm

This paper focuses on the issue of tracking the trajectory of a flexible arm. The purpose is to ensure the flexible arm follows the desired path in the joint space. To achieve our objective, we have three problems to solve: modeling, control, and trajectory planning. As in the case of rigid robots, the EulerLagrange formulation remains valid with the exception of dividing the flexible arm into ...
