Abstract
This paper describes a positioning system with a linear DC servo motor (LDM ) under self-tuning fuzzy control. Two types of self-tuning fuzzy controlle rs (STFCs), one a model reference type, the other a feedforward type, are p roposed. The objectives of these two types of STFCs are to repress the infl uence of nonlinear characteristics of the LDM and to improve the tracking p erformance. The fuzzy rules in the STFC are adjusted by a tuning algorithm so that the tracking error converges to zero. The effectiveness of the prop osed STFCs for improvement of the tracking performance is demonstrated by t he experimental results.
