CELSM MAGNETIC LEVITATION SYSTEM CONTROL USING FSMC-PID

Abstract

In a magnetic levitated system, the object is suspended without any kind of contact other than magnetic fields. Main application of this magnetic levitation is seen in maglev trains. Nowa days, all focus in this field is for creating a high speed, smoother and quieter vehicle system. Maglev trains benefits more to industry than conventional trains such as low maintenance cost, high speed, less affected by weather, increased power efficiency, less noise and many more. The significant area to be checked is the control part of a maglev system so that it can provide more efficient results. The fuzzy based SMC control of the MAGLEV system of the controlled excitation linear synchronous motor (CELSM) with PID as current controller is presented in this work. The simulation model is created and compared to other control methods. The results show that better maintenance of the magnetic levitation air gap is obtained under FSMC-PID control strategy, as well as the ability to deal with changes in the magnetic levitation system. The feasibility and superiority of the modified control method have also been demonstrated.
