Nonlinear Simulink Model Of Magnetic Levitation Laboratory Plant

Abstract

The paper deals with modelling of a magnetic levitation laboratory plant. The goal of the work was to create a nonlinear model in a MATLAB / Simulink environment representing behaviour of a real-time CE152 laboratory plant. The CE152 is a magnetic levitation model developed by Humusoft company. From the control point of view, the CE152 magnetic levitation plant is a nonlinear very fast system. The model of the plant is developed using first principle modelling and subsequently made more precise using real-time experiments. The behaviour of the resulting Simulink model is compared with the behaviour real-time plant. The Simulink model can be further used in the process of controller design.

Bu bölümde α parametresi için bir kestirim algoritması kullanılmamış, sistem davranışları gözlemlenerek en iyi sonucu alacak şekilde α = 0.4 değeri seçilmiştir.…”

Modelling And Model Predictive Control Of Magnetic Levitation Laboratory Plant

“…The process of creating a mathematical model of the CE152 Magnetic Levitation laboratory plant is described in detail in (Chalupa et al 2016). This chapter presents just results important for a design of a control system.…”

“…Moreover, controllers based on nonlinear models are in general more computationally demanding and thus are not suitable for fast systems. This paper is based on previous work (Chalupa et al 2016) where detailed nonlinear Simulink model of the CE152 Magnetic Levitation plant (Humusoft 1996) is presented. The model was derived using first principle modelling (Himmelblau and Riggs 2004) and values of the model parameters were specified by real-time measurements.…”

Magnetic Levitation – Modelling, Identification and Open Loop Verification

“…Modelling and identification problematics of the magnetic levitation process can be found e.g. in [9,10,[13][14][15][16][17][18][19][20][21]. Usually first principle model is derived, and the unknown parameters are estimated from experimental data.…”
