Fuzzy compensator for stick-slip friction

Abstract In this paper we propose a fuzzy compensator to implement the position control of a 1 d.o.f. mechanical system with stick-slip friction. With this fuzzy compensator many advantages can be obtained—the ability to use the sliding mode control theory, higher robustness with respect to disturbances and easy implementation to another position control system.

Reliability based lifetime prediction and optimization for permanent magnet synchronous machines

This paper presents a methodology for on-line evaluation of electrical motors current state, used to predict its life-time and to increase the residual lifetime. Based on the estimated motor state, the residual lifetime can be extended drastically by reducing the load. Also maintenance costs can be reduced.
