<Abstract>

This paper proposes an application of adaptive SMC strategy using SAC for a single-input singleoutput (SISO) magnetic levitation (maglev) system to deal with the difficulties in standard SMC caused by the requirement of thorough knowledge of controlled plant parameters and dynamics. The role of SAC is to construct an equivalent control input of adaptive SMC. For constructing a corrective control input, this paper applies the conventional method using sign function with a modified sliding surface. Hence, no any prior knowledge of the controlled plant is required for calculating equivalent control law. Finally, the experiments of the application of the control method are executed and the effectiveness of this control system is confirmed.
