Research of Magnetic Bearing Control Based on Fuzzy Logic and Single Neuron

For the highly nonlinearity and unstable ability of the AMB system,a fuzzy-neuron control approach is proposed in this paper by combining the fuzzy logic scheme with single neuron control to improve the performance of the control system.Fuzzy logic control is adopted with proper single neuron control when system error is big;two controllers are both working when error is small.This controller overcomes the defaults of the fuzzy control which has steady state error and the single neuron control which dynamic performance is not very well.Simulation results demonstration that the proposed controller not only improves the dynamic performance of AMB system but also has high disturbance rejection ability.
