Original Abstract

The active magnetic bearing (AMB) control is a complex problem, as it is fast, unstable and nonlinear system. The contribution deals with the simulation verification of AMB control using conventional PSD controller with nonlinear forward compensator. The automated universal approximator based on locally weighted learning (namely Receptive Field Weighted Regression – RFWR method) is used as the compensator. The paper shows the improvement of control quality criterion over conventional controller (approx. 2.5x) and furthermore the results of test of robustness against overtraining, when control is not disturbed by noise; test of robustness against the noise; test of robustness against the action delay and test of robustness against noise and action delay combination.
