【Abstract】 A control strategy named PDF control is used in permanent magnet electromagnetism bearing controlling and the model of PDF control system is founded. By analyzing the features of PDF control system on PMEB (permanent magnet electromagnetism bearing) and simulating the results through computer, it is proved that PDF control system has such virtues as high stability, high precision, good robustness, easiness in control and so on.更多还原
