Analysis of PID Controller Parameters Influence on Dynamic Properties of an Active Magnetic Suspension

Resumo

The paper considers the issues of justification and choice of the stiffness and damping values for the active radial magnetic bearing depending on the preset “negative” stiffness of the suspension and the dynamic behavior of the rotor. We present an algorithm for continuous adjustment of the basic parameters of the PID regulator in the operating range of rotor speeds that provides the adaptive control of stiffness and damping for radial magnetic.
