- 中文摘要: 對於使用直流電磁鐵之磁浮系統,本文提出一種具有高可靠度的控制器。設計此控制器時,几電子放大器動態、受控體非線性、以及受控體參數之不確定性,均加以考慮,並採用滑動模式控制設計控制法則。最後,將此控制器實際應用於所建立的實驗系統。實驗結果顯示:實驗系統在使用同樣的控制器的情況下,不僅能可靠地懸浮於任何所需的操作點,而且其動態特性不因操作條件的改變而有顯著的變化。
- 英文摘要: A reliable controller for magnetic suspension systems with controlled DC electromagnets is proposedin this paper. In the controller design, amplifier dynamics, plant nonlinearity, and plant parameteruncertainty are all considered, and then the sliding mode control principle is used to develop the controllaw. The controller has been successfully implemented in an experimental system. The system can bereliably stabilized at any desired operating point without any modification of the controller, and its dynamicbehavior does not exhibit significant differences under different operating conditions. These facts areverified by experimental results.
