摘要：
In the last decades, as a typical nonlinear system, active magnetic bearings (AMB) system has been widely applied in manufacturing systems. A sliding mode control (SMC) scheme for the AMB system is proposed with the disturbance observation of the linear extended state observer (LESO) in this paper. The chattering of the AMB system has been reduced by LESO-SMC by at least 60%. Sufficient BIBO (bounded input-bounded output) stability conditions of the closed-loop AMB system governed by the proposed LESO-SMC are derived by Lyapunov theory. Finally, experiments are conducted to verify the effectiveness and superiority of the proposed LESO-SMC than conventional SMC.
