Application of intelligent control method in magnetic bearing

Active magnetic bearing (AMB) is a new kind of base mechanical component that can supply contactless support. Its working principle involves contactless support of the axle by the bearings through electrical magnetic force. So, AMB has some good features, such as no touch friction and wear, small motion resistance, lower power supply and long utility time. Overseas, AMB technology has reached mature level and increasingly products, which set up with AMB, can be found. The ways of design and process AMB rotor system are described. Here a number of design methods of AMB are dealt with, mainly includes the features in the systematic design, methods of design for the system controller, rigid shaft system and flexible shaft system. Some numeric results are presented also.
