Robot Trajectory Control System Design for Multiple Simultaneous Specifications: Theory and Experimentation

Abstract

A new control design method is developed to satisfy multiple specifications simultaneously. The proposed convex combination method is applied to a six (6)-degree-of-freedom commercial robot. In a trajectory tracking task under external disturbance, four requirements, stability, path accuracy, velocity accuracy, and steady-state error of position, can be met at the same time. The experimental results verify this conclusion.
