Magnetic levitation system based on quadratic optimal control

Abstract

This article mainly discusses the structure and basic principle of magnetic levitation system, by the structure and principle of magnetic levitation system, the nonlinear mathematical model is established and the model was linearized processing analysis of the controllable observability based on this, the system controller design, make the system stable, and select the linear quadratic optimal control to control system, and simulated in MATLAB, the results show that the selection of different QR matrix will be relatively large impact on the results of control performance.
