Abstract
A complete model of four radial degrees of freedom self-sensing magnetic bearing systems which includes all interactions between the different degrees of freedom is presented. A new method for controlling self-sensing magnetic bearings with unbalance compensation is also presented. The method utilizes the Q-parameterization theory. The Q-parameterization controller is an observer-based stabilizing controller with a free parameter Q, and that it is suitable for robust control of self-sensing magnetic bearings. The free parameter Q can be chosen through optimization to achieve robustness, noise minimization, and unbalance compensation. Unbalance compensation is achieved in three different ways: airgap regulation, current regulation, and force regulation.
