本論文主要目的是發展一套造波機系統之人機介面，此系統是以造波理論為基礎，結合伺服馬達控制架構，針對海洋工程實驗之規則與不規則波的需求，所設計出的人機介面，其功能包含造波控制、實驗訊號擷取、資料統計、波譜分析等。在跨領域系統整合下，針對海洋工程實驗量測與統計分析方法，架構人性化操作控制介面。
本研究實驗於國立成功大學系統及船舶機電工程學系流力實驗室小型斷面水槽中進行，水槽長10公尺、寬0.3公尺、高0.3公尺，以活塞式造波機構，利用伺服馬達驅動，採用美商國家儀器公司的NI-PCI-7342做為伺服馬達運動控制卡，並以該公司的圖控程式語言LabVIEW及FlexMotion做為人機介面編輯軟體。
本研究實驗中針對某固定水深及波高條件下，依理論公式H/S比值，把波高轉換為造波板行程，測試不同頻率之規則波，並將測試結果繪圖，以實測波高與造波板行程之比值為縱座標，造波頻率為橫座軸，經迴歸取六次多項式，以此做為波高轉換行程之修正公式。由於此修正公式為頻率函數，在不規則波產生實驗中，對於各成份波可依其頻率換算求得波高與造波板行程之比值。經比較修正公式與理論公式之實驗結果，得知利用修正公式可降低波高誤差。
對於波高誤差修正，本研究是以閉迴路回授控制方法，利用波高計量測水位訊號，經擷取一段時間分析出示性波高與目標波高之誤差，做為波高命令之修正值，經實驗測試結果，無論規則波或不規則波實驗在經過多次修正後，波高誤差可控制在1%以下之精確度。

The main purpose of this thesis is to develop a human machine interface for a wave making system. In this system, the fundamental wave making theory is combined with the control of the servo motors to satisfy the demand of regular and irregular waves made for ocean engineering experiments. The designed human machine interface includes functions such as wave making control, experiment signal acquisition, data statistics, spectrum analysis, and so on. The system involves multidisciplinary integration, aiming to provide conveniences for experimental analysis and offer a user-friendly operation interface.
The experimental study is conducted in a small-scale section water tank placed in the Department of Systems and Naval Mechatranic Engineering, National Cheng Kung University. The water tank has a size of 10m in length, 0.3m in width and 0.3m in height. The piston type wave maker is driven by a servo motor which is controlled by the NI NI-PCI-7342 motion card. The human machine interface is composed and edited using LabVIEW and FlexMotion.
Under the condition of a fixed water depth and height, the wave height can be transformed to a corresponding paddle stoke according to the theoretical H/S ratio formula. A series of regular waves are first tested at different frequencies, and the experimental results are plotted with the wave high stoke ratio as the ordinate and the wave frequency rate as the horizontal axis. To practically generate required waves, this theoretical formula requires revision amendment, which is performed by regression from the above testing results. Comparing the wave generation experiments between the theoretical formula and the modified method, it is found that the latter is capable of significantly reducing wave height errors.
The closed-loop feedback control is applied in this study. A wave height probe is used to measure the water elevation as the feedback signal to the control system. The experiment shows that the error can be confined within 1% such that high accuracy wave making can be achieved.
