Sliding mode controller for magnetic levitation system comparatives studies

Abstract

The objective of this paper is to synthesize a regulator based on sliding modes for the control of a magnetic levitation system and to compare the performances of this type of regulator with other regulators namely: PID, fuzzy regulator.

The simulation results show the merits of the sliding mode technique since it is robust against disturbances and parameter changes in the model. The advantages and disadvantages of each regulator are outlined in the form of a simulation curves.
