ABSTRACT:
A non-linear control type magnetic bearing comprises a pair of electromagnets for magnetically attracting an object so as to permit it to be levitated therebetween, a current supply circuit for alternately supplying an excitation current to the pair of electromagnets, a circuit for generating a pair of current level signals corresponding to the levels of the currents through the respective electromagnets, a velocity sensor for generating a velocity signal corresponding to a velocity with which the object is moved, a difference circuit for generating a difference signal corresponding to a pair of current level signals, a differentiating circuit for differentiating the velocity signal to generate an acceleration signal corresponding to the acceleration rate of the object, an analog operating circuit for generating a position displacement signal corresponding to the position of displacement of the object by substituting a difference signal and acceleration signal into an equation of motion of the object, and a switching discriminator circuit for identifying a positive or a negative sign of a linear equation of the position displacement signal and velocity signal and for supplying to a current supply circuit a switching signal which alternately switches a supply of current to the respective electromagnets.
