本文從黑箱建模的角度出發，分析高溫超導磁懸浮系統和常導磁懸浮系統在穩態懸浮
時的動態特性。此外，通過對比實驗，還比較了磁懸浮系統穩態懸浮時高溫超導磁體與普通磁體的電磁特性異同。研究結果表明，雖然高溫超導磁懸浮系統和常導磁懸浮系統動態特性的傳遞函數模型不同，但從控制的角度看，它們的電磁特性并無明顯區別。在系統的工作頻段內，高溫超導磁體線圈自感應給其電磁特性帶來的影響可以忽略。

Abstract: By black box modeling, we compare dynamic characteristics of High Temperature
Superconducting (HTS) electromagnet based magnetic levitation system with that of general
electromagnet based magnetic levitation system when electromagnets are stably suspended.
Furthermore, we have investigated electromagnetic characteristics of HTS electromagnet and
general electromagnet by comparison experiments. The result of study shows that the transfer
function models which describe dynamic characteristics are different, however, from the control engineering point of view, their electromagnetic characteristics are similar. In the frequency bands of magnetic levitation systems, influence on the electromagnetic characteristics due to self-induction of HTS coils can be ignored.
