Abstract

This paper studies fractional-order (FO) position/force algorithms in the hybrid control (HC) and the cascade control (CC) of manipulators. The system performance is analyzed, in the time and frequency domains, and the effects of joint backlash and flexibility are investigated. The results show that the FO algorithms and the CC architecture have superior robustness and stability.
