Abstract

Abstract:

This paper put forward a vision that designing a fuzzy adaptive fractional PI ^λ controller based on the traditional PI control combining the widely used fuzzy control theory and the fast developing fractional theory. Meanwhile dynamic simulation for the feed servo system is done under the SIMULINK,which results show that the servo controller designed in this paper has superior control performance and the adaptive fuzzy fractional PI ^λ can meet the control requirements of high precision servo system. The idea is feasible.

Key words: Traditional PI control, servo control system, fuzzy adaptive fractional PI ^λ, Simulink
