| Summary: | 碩士 === 國立交通大學 === 控制工程系 === 85 === Magnetic levitation system have these advantages such as
friction-less, low rub, and maintain-free. Its applications can
cover these field of mass transportation, motor bearing, etc.
Due to the recent advent of the rare-earth high-energy-product
permanent magnet, it has become feasible to control a MAGLEV
system using hybrid magnet with near-zero current dissipation.
This paper proposes a sliding-mode control algorithm applied to
the zero-power control of a hybrid magnetic levitation system.
The controller designed here is highly robust and suitable for
control of systems with heavy nonlinearity, which characterizes
the MEGLEV system. Therefore, expected control performance
could be attained. In addition, model following sliding-mode
control algorithm is proposed to improve the transient response
and the effects are demonstrated by simulation results.
