Non-linear Fuzzy Logic Control for Forced Large Motions of Spinning Shafts

Abstract

A unique control approach is developed for prescribed large motion control using magnetic bearings in a proposed active stall control test rig. A "nite element based, #exible shaft is modeled in a closed loop system with PD controllers that generate the control signals to support and to shake the rotor shaft. A linearized force model of the stall rig with 16 magnetic poles (4 opposing C-cores) yields stability and frequency responses. The non-linear model retains the non-linearities in Ampere's law, Faraday's law and the Maxwell stress tensor. A fuzzy logic control system is then designed to show the advantages over the conventional controllers with the fully non-linear model. ( 2000 Academic Press
