臺灣博碩士論文加值系統

一般文獻中所採用的磁浮系統模型，常常忽略一些如漏磁、邊緣磁場、有限鐵心導磁率等實際物理效應，若以此簡化模型所設計之控制器，應用於實際系統上，可能使其性能受到限制。為提昇控制系統性能，故需準確知道磁浮軸承系統的真實動態為何。
本文將以多輸入多輸出(MIMO)的磁浮軸承系統為對象，針對其徑向軸承做MIMO之系統鑑別實驗，利用HP3563A控制系統分析儀，經由系統鑑別實驗的過程，來修正理論模型與實際系統的差距。再以鑑別的模型，設計LQR(Linear Quadratic Regulator)及LQG/LTR(Linear Quadratic Gaussian with Loop Transfer Recovery)的線性控制器，透過dSPACE即時控制系統來實現控制器，達到轉子高速旋轉之目的。
