Design a Nonlinear Control Using Exact Input-Output Feedback Linearization for CE152 Magnetic Levitation

Abstract

Technological advances necessitate intelligent control rules in order to achieve tight specifications, which underlines the growing importance of nonlinear control systems. A magnetic levitation benchmark is a non-linear system that’s popular among engineers. Because of the considerable nonlinearity in the modelling process of such systems, many researchers in the control engineering field have found analysing the controller’s performance to be a challenging experience. The objective of this research is to use an exact input–output feedback linearization approach to develop a control scheme for a magnetic levitation system. This work presents a dynamic magnetically levitated simulations based on the mathematical description of the nonlinear system. The levitation simulation model is incorporated into a control system with the aim of preserving a steady state specified by a desired trajectory, which is simulated by Matlab/Simulink.
