| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系 === 87 === With the melioration of magnetic elements in these years, the applications of magnetic levitation (MAGLEV) system cover more and more fields like mass transportation, motor bearing, etc. Friction-less, low rub, and maintenance-free are attractive advantages of the MAGLEV system.
This paper proposes a sliding-mode control (SMC) algorithm and applies to the position control of an originally unstable hybrid MAGLEV system. With highly robust characteristic, the sliding-mode controller is suitable for controlling nonlinear systems like the MEGLEV system. In addition, a new algorithm for choosing sliding vector is used to improve the conventional algorithm and meliorate the system response. The SMC will be demonstrated in numeric simulation.
