本論文旨在設計主動式磁浮軸承(Active Magnetic Bearing, AMB)之全系統故障診斷(Fault Diagnosis)方案。傳統故障診斷方式皆以單獨診斷致動器(Actuator)或感測器(Sensor)為主，且同一時間內僅能診斷一個故障點，本研究則結合兩種診斷方法，同時利用狀態估測器(State Estimator)與參數估測器(Parameter Estimator)進行磁浮軸承系統感測器與致動器故障診斷，且提出新式診斷方式，結合狀態估測與邏輯判斷法則，除了增加診斷精確度，並能同時偵測出兩個以上的故障點，再配合電腦模擬驗證此邏輯判斷法的正確性。本研究最後利用磁浮軸承系統與dSPACE 數位類比資料轉換與擷取設備，搭配MATLAB/Simulink程式語言進行全系統診斷實驗，以一連串實驗證明本文所提故障診斷方案之可行性。

This thesis proposes a full system fault diagnosis algorithm for active magnetic bearings (AMB). Most traditional approaches for fault diagnosis are based on actuator and sensor diagnosis individually and only can diagnose a single fault location at a time. This research combines two diagnosis methodologies by using both state estimators and parameter estimators to diagnose actuator and sensor faults in rotor/AMB systems. The proposed approach not only increases the diagnosis accuracy, but also detects more than two fault locations simultaneously. The presented logic analysis and algorithm have been verified by computer simulations and intensive experiments. The test rig is equipped with AMB, dSPACE, data aquizition unit and MATLAB/Simulink simulation environment.
