TLDR
The levitation system of high speed electromagnetic system (EMS) MAGLEV-vehicles has been successfully controlled by sliding mode control (SMC), which is robust with respect to parameter variations and force disturbances but fails to compensate guideway disturbances just like linear controllers.Abstract:
The levitation system of high speed electromagnetic system (EMS) MAGLEV-vehicles has been successfully controlled by sliding mode control (SMC). This nonlinear control method is robust with respect to parameter variations and force disturbances but fails to compensate guideway disturbances just like linear controllers. To maintain the desired robustness and minimize the effect of guideway disturbances SMC is combined with a linear disturbance observer whose weighted output is added to the set point. Various simulations using an extensive nonlinear model show the excellent performance of the new approach. >read more

TL;DR: In this paper, an experimental comparison between a sliding-mode controller and a classical controller for stabilizing and commanding a magnetic levitation system is made, where the sliding mode method can be applied to a nonlinear system in the global sense, and the issues of performance and robustness to modeling uncertainties and disturbances can be directly incorporated in the design as tradeoff parameters.

Sliding mode control with perturbation estimation (SMCPE): a new approach
Hakan Elmali,Nejat Olgac +1 more
TL;DR: In this paper, an estimation process for dynamic perturbations is employed jointly with the sliding mode control (SMC) technique, which offers a robust feedback control with much lower gains than its conventional counterparts against slowly varying perturbation.
