Digital implementation of a magnetic suspension control system for laboratory experiments

In this paper a digital control experiment using a magnetic suspension syst em is described. Although the results presented are for a quadratic optimal controller, the control system configuration used can cope with more advan ced real-time control algorithms. Practical issues concerning parameter ide ntification, computer simulation, discrete-time implementation, use of a di gital signal processor based controller and filter design are addressed. Si mulated and experimental responses are presented and analyzed, Finally, a d etailed plan on reproducing the control experiment is included.
