Robust Control Design for an Active Magnetic Bearing System Using Advanced Adaptive SMC Technique

Fast rotating machines require special attention to ensure accurate rotor placement within the air gap. For this reason, the active magnetic bearings (AMB) system is used to levitate the rotor in the air gap using an electromagnetic feedback control force. The contact-less support AMB system improve...
