Design, implementation and self-tuning adaptive control of maglev guiding system

This paper presents a self-tuning adaptive control (STA control) for a magn etically levitated (maglev) guiding system. The guiding system is a repulsi ve maglev system with a. passive carrier and four active guiding tracks. Hy brid magnets exert the levitation forces, whereas the stabilizing forces ar e produced by electromagnets. Given such a system, an STA stabilizing contr oller is developed, and the thorough analysis of the stability property is also proposed. It is shown that without precise knowledge of various compon ents, the overall system stability and the regulating precision are assured , which validates the hereby proposed system. From the simulation and exper imental results, the performance of the system design and the enforced cont rol mechanism is demonstrated successfully. (C) 1999 Elsevier Science Ltd.
