| dc.title | Design and analysis of an analogue controller for an electromagnetic suspension system | en_US |
| dcterms.abstract | The electromagnetic suspension (EMS) system is a closed loop position control system. The electromagnet (e.g. controlled DC electromagnet) is levitated above a ferrous body by using some appropriate sensors as feedback. The magnetic suspension system is very useful for transportation. It can save power, avoid air and sound pollution, provides fast and quiet conditions for the factory, etc. The dissertation first briefly reviews the mathematical modelling and analysis of nonlinear feedback linearizing control for an electromagnetic suspension (EMS) system. Advanced control algorithms are studied and a number of alternative feedback controllers are proposed which are expected to be robust against mass parameter perturbation and force distribution. Simulations of the controllers are used to investigate the performance of the EMS system. Some tests are also performed to derive experimental results to gain insight for the hardware implementation as a low cost controller. | en_US |
