中文摘要 | 本文研究目的為提出一種非奇異終端滑模控制(Nonsingular Terminal Sliding Mode Control, NTSMC)的方法應用於主動式引擎懸吊系統(Active Engine Mounting System, AEMS)的振動控制。由於汽車於行進間或是路邊停車時所遭遇到的外加干擾(路面狀況、引擎怠速…等)並非事先可以預期,另外汽車引擎的相關參數(質量、阻尼與彈力常數)於運作時並非固定值,因此非常適合利用具備強韌性的滑模控制原理來設計AEMS 的控制系統。根據Lyapunov 穩定定理,本文所設計的NTSMC 可以確保閉迴路系統的穩定性,另外由數值模擬結果可發現,使用NTSMC 後可有效地降低引擎怠速時所造成的振動和抵抗不同類型的外加干擾。 |
英文摘要 | In this study, the active engine mounting system (AEMS) for vehicle to isolate the vibration of engine body by utilizing nonsingular terminal sliding mode control (NTSMC) is discussed. In practice, system parameters of engine are uncertain and external disturbances applied to the vehicle are not predicable. Sliding mode control is a well-known and robust approach to control the overall system with undergoing system uncertainties and external disturbances. Based on the Lyapunov stability theorem, a NTSMC applied to AEMS is introduced. It is shown that the occurrence and stability of the sliding motion of the proposed SMC is guaranteed. To evaluate performances of the proposed controller, four types of external disturbance are involved. Numerical simulations show that the proposed controller is able to isolate the vibration of engine body and cope with various types of external disturbance as well. |
