中文摘要 | 本論文針對油壓致動之懸吊系統,設計滑動模式控制器以進行控制。因為油壓致動懸吊系統具有非線性時變之特性,若要建立系統正確之動態數學模式是不容易的。因此,本研究利用透過系統鑑定所估測之線性數學模式來近似油壓致動懸吊系統,進一步設計滑動模式控制器來進行控制。透過實驗結果之驗證,本研究所設計之控制器能夠有效抑制車體在行經巔坡路面時所造成之車體振動量與加速度。 |
英文摘要 | This paper presents a practical design and implementation method of a sliding-mode controller (SMC) for a hydraulic actuating suspension system. Since the hydrauling actuating suspension system has nonlinear, time-varying behavior and complicated mathematical model, it is difficult to establish an accurate dynamic model for model-based control design. Hence, a linear time-varying model estimated from the system identification method is selected to approximate this nonlinear suspension system. The sliding-mode controller was designed based on the identified model for the hydraulic actuating suspension system. The experimental results show that the designed controller effectively suppresses the oscillation amplitude and acceleration of the vehicle sprung mass correlating to the road variation and external uncertainies. |
