“…At the last from the time span of t > 2.39 secs to 3 secs the ball mass is changed again to the actual mass of the ball. Table (2) shows the value of the ball position, current and control input for the different mass of the ball. The values in table (2) are almost equal to the actual values which is calculated in section (5)…”

A robust-optimal control approach for an electromagnetic levitation system with matched and unmatched uncertainties is proposed in this article. Because of the uncertainties in the dynamics of an electromagnetic levitation system, it is necessary to design a robust control law that will ensure the stability of the system in the presence of these uncertainties. In this framework, the dynamics of an electromagnetic levitation system are addressed in terms of matched and unmatched uncertainties. The robust control problem is translated into the optimal control problem, where the uncertainties of the electromagnetic levitation system are reflected in the cost function. The optimal control method is used to solve the robust control problem. The solution to the optimal control problem for the electromagnetic levitation system is indeed a solution to the robust control problem of the electromagnetic levitation system under matched and unmatched uncertainties. The simulation and experimental results 1 demonstrate the performance of the designed control scheme. The performance indices such as IAE, ISE, ITAE, and ITSE are compared for both uncertainties to showcase the robustness of the designed control scheme.

“…Recently, magnetic levitation (MagLev) systems have been extensively researched for transporting logistics in various manufacturing plants as well as traditional transportation methods such as trains [ 1 , 2 , 3 , 4 ]. The studied MagLev systems are being considered to replace the existing belt-type conveyor system in the semiconductor and OLED display panel production process [ 3 , 4 , 5 , 6 , 7 ]. These processes require a highly clean environment because fine dust has a significant impact on production yield [ 8 , 9 ].…”

“…This type of MagLev logistics transport system is divided into an on-board type and an in-track type depending on the location of the power device for electromagnetic suspension (EMS) [ 2 , 3 , 4 ]. In this paper, we consider an attracted superconducting hybrid (SH) electromagnetic suspension (EMS) [ 10 , 11 ].…”

Recently, magnetic levitation systems have been applied and studied in various industrial fields. In particular, in-tracktype magnetic levitation conveyor systems are actively studied since they can effectively minimize electromagnetic effects in processes that require a highly clean environment. In this type of system, diverse and multiple sensors are structurally required so that the control performance of an integrated system is primarily governed by the slowest measuring sensor. This paper proposes a multisensor fusion compensator to integrate the outputs obtained from various sensors into one output with the single fastest time rate. Since the state of the system is estimated at a fast time rate, the optimal controller also guarantees fast performance and stability. The computation of electromagnetic fields and the control performance of the considered superconducting hybrid system were analyzed using a computer simulation based on finite element methods.
