Mathematical Modeling of Electromagnetic Levitation Based Active Suspension Using Bond Graph

Abstract

This paper offers motivation for modeling and simulation of an electromagnetic levitation based active suspension system (EMLASS) using bondgraph. Model of EMLASS contains 2 electromagnets as an unsprung mass and one magnet as sprung mass. Levitation based suspension is a novel technique to develop an active suspension over current technology. It has a high dynamic capability which is more sensitive for the road irregularities and its advantage is to provide additional stability to eliminate the effect of road irregularities. Our goal is to develop mathematical modeling and bondgraph modeling of EMLASS.

Bond Graph-Based Modelling and Control of Electromagnetic Levitation System Using Firefly Optimization

“…The control techniques mentioned above are based on non-linear or linear mathematical models, allowing their developers to simulate and/or implement them in practice, giving acceptable results. However, there is some literature work on graphic modelling by the bond graph tool, which treats the MAGLEV system as a magnetic device or circuit (Longoria, 2002) (Karnopp et al, 2012), used as a sensor or transducer (Grivon, 2017), part of a record memory circuit element (Calchand, 2014), electromagnetic suspension used in vehicles or others (Hayoun et al, 2004) (Mishra et al, 2013) (Mishra et al, 2014) (Clemen et al, 2016), actuating element in mechatronics (Merzouki et al, 2013) (Das et al, 2005) (Niţu et al, 2017) and robotics (Niţu et al, 2008).…”
