abstract
1993 IEEE. Low velocity control of DC motors is important in precision engineering applications. The stick-slip oscillation caused by Coloumb friction between the commutator brushes and the rotor is especially predominant at low speeds. In this paper the authors present a fuzzy feedback cancellation scheme of this stick-slip oscillation. The authors use the system ODE and a stick-slip rule base to estimate the static and dynamic effects of friction. Finally, the authors discuss the broader implications of this scheme and raise some issues for future research.
