本論文研究以亥姆霍茲線圈(Helmholtz Coil)開發一個可程式設定動態磁場的2米直徑磁場校正艙，用以校正磁力計、測量酬載機構的殘磁以便修正抵消、以及模擬在太空中飛行的實測的動態磁場。本平台透過前饋與回饋控制依規劃產生變動的磁場。磁場規劃的設定有靜態磁場以及動態磁場兩種模式。使用者可以透過人機介面將變動的磁場作時序排程，並監測線圈的電流和磁場動態。校正艙的系統、機構、電路、軟體、以及人機介面的設計已經過實驗驗證，並以"硬體在迴路"之應用加以確認系統的實用性。校正艙的磁場設定之動態範圍涵蓋±100000nT、解析度達0.19nT、精確度<2nT、磁場的更新頻率可達270Hz、改變設定後達到穩定的時間為13ms。 A two meter diameter magnetometer calibration Helmholtz chamber is developed. Dynamic magnetic field scenarios as well as static test field can be programmably generated through a human-machine interfaces (HMI). The magnetic field is controlled to follow the setup scenario by both feed forward and feedback schemes. The electric currents in the coils and the resultant magnetic field are monitored and logged through the programming interface. With this chamber, a magnetometer can be calibrated, the inherent magnetic field bias in a payload structure can be measured and calibrated out, and an actual in-flight magnetic field scenario can also be emulated for a hardware-in-the-loop (HIL) test. The system, mechanical design, circuits, control software, and the HMI are tested and its applications are proven practical and convenient. The measurement specifications achieved are a standard deviation of 2nT with the resolution of 0.19nT in the dynamic range of ±100000nT. The magnetic field setting can be updated at the maximum rate of 270Hz while the settling time is 1.3m sec after each magnetic field set point change
