【Abstract】 The technology of Active Magnetic Bearing (AMB) is now spreading throughout the world. Here the rotor-AMB system is studied in several different respects. We set up a more accurate model for the control object, study three kinds of controllers, and respectively compare their specifications such as system stability margin, dynamic performance and steady-state accuracy. This paper also presents the negative influence of phase-lag network which is widely used in AMB linear controller. The detailed analyses in this paper will make it a good reference to the designing Of the AMB control system.更多还原
