Abstract

Centrifugal force caused by eccentricity in a vertical magnetic bearing (VMB) is dealt with an innovative design by featuring 1)3-pole 2)6-step 3)PD fuzzy switching controller 4)hybrid controller. The hybrid controller is composed of a fuzzy switching controller and a traditional ID controller. Fuzzy switching controller regulates the instability of plant when pump shaft deviates by a small perturbation from the nominal gap. The traditional ID controller compensates for the centrifugal force caused by eccentricity. In the simulation, 6-step switching works as a relay race in terms of a competitor. Simulation results approve the approach developed in this paper be feasible to overcome the effect arisen from eccentricity.
