Abstract: Magnetic bearing with redundant structure can regain
supporting ability by way of reconstruction under the condition of coil
failure. In this paper, the influence of parameters on stiffness is studied
by way of simulation and experiment using PID control algorithm, and the
reconstruction strategy is proposed. The range of feasible parameters of
redundant reconstruction is determined and the weight of the parameters is
found out. The control parameter that makes stiffness of magnetic bearing
constant is found out. The experimental results are in agreement with the
simulation results in tendency, but the experimental results are less than
the simulation results.
Keywords: Magnetic bearing, coil failure, reconstruction stiffness, PID control algorithm
