Abstract :
This paper presents a hybrid control approach of a self-tuning fuzzy controller plus a proportional-derivative controller (STF+PD controller) for wide range operation of a large-gap magnetic suspension system. Since the magnetic suspension system is highly nonlinear and inherently unstable in operation, the proposed STF controller is used to overcome the nonlinearity of wide range operation, and the PD controller is applied to stabilize the control system. Both simulation and experimental results show that the STF+PD control approach is successful to wide range control of the magnetic suspension system
