Control of Flexible Robot Arm



Jonathan W. Lee, L Haynes, B Wang, T M. Tsai


This work is a computer simulation of the control of flexible robot arm. The dynamic equations for a single-link flexible robot arm have been derived rigorously. This arm has two degrees of freedom in rotation and one in translation so that the workspace is three-dimensional. The payload is simulated by attaching additional mass to the arm at a specified location. The governing equations of the plant and the measurements are non-linear. The process of control is divided into two stages: coarse control and fine control. Based on the pole-placement method, a linear observer is constructed for fine control. The numerical results of several cases are presented here. The effects of damping and sampling rate are also discussed.
