Contribution to fractional-order adaptive control for parallel kinematic manipulators : application to VELOCE robot

Abstract

This study focuses on the VELOCE robot, a 4-degree-of-freedom parallel manipulator. By incorporating fractional order control methodologies, the thesis proposes enhanced fractional adaptive controllers—a fractional Model Reference Adaptive Controller with Proportional-Derivative feedback and a fractional L1 adaptive controller with feed-forward terms. The aim is to optimize performance and improve robustness.
