To improve the steady performance of the system, a fuzzy - pid combined controller is applied to the magnetic bearings system : applying fuzzy control in a large error range ; applying classical pid control in a small error range. the simulation results show that this kind of control strategy can make the rotor of the magnetic bearings stabilize in a large range
本文首先設計了基本模糊控制器,並用matlab進行了模擬研究,為了改善系統的穩態性能,本文提出採用模糊- pid復合控制器,在大偏差范圍內採用模糊控制,小偏差范圍內採用傳統pid控制,並進行了磁懸浮轉子起浮特性的模擬,模擬結果表明這種控制策略有利於使磁懸浮轉子在大范圍內穩定。Applying magnetic suspension technique to the supports of hdd ( hard disk drive ), it have a lot of advantages in comparison with other bearing types, for example, contact free, absence of mechanical friction and wear etc. in design of hdd suspended by amb, it is one, of difficulty and emphases that active control for rotor according as the signal of displacement
將磁懸浮軸承應用於硬盤的支承,完全消除軸承與硬盤轉子的機械接觸,使硬盤具有其它軸承支承的硬盤無法企及的特點。在磁懸浮硬盤設計中,傳感器檢測的轉子位移信號是控制器對軸承進行主動控制的依據,是整個系統研究的重點和難點之一。The traditional molecular pump with popular bearing can not meet the challenge of semiconductor manufacturing because of the vibration, short life, unpure vacuum and so on. so it is very important to design the magnetic bearing and power amplifier for molecular pump
本課題研究的目的是,解決傳統軸承型分子泵應用在半導體製造行業時出現轉速低、壽命短、真空不潔凈等問題,設計分子泵的磁懸浮軸承結構和功率放大器,對實現分子泵在半導體工業中的良好應用有著重要的意義。The calculation expressions of electromagnetic support forces of the spherical magnetic bearing and the calculation expressions of turning moment for the spin axis of flywheel rotor are presented. the dynamic model in radial translation and in rotation, as welll as the movement simulation with the widely used control method pd was proposed independently
並按照設計的基本結構,推導了球形磁懸浮軸承的電磁承載力的計算式和偏轉電機提供的偏轉力矩的計算式,並將轉子的運動分為平動和轉動兩部分分別進行了動力學分析,給出其運動方程。分享友人
