以影像視覺做為位移感測之迴授,由於取樣頻率較傳統接觸式感測器低與影像處理造成的時間延遲,使得高頻材料試驗中,控制性能較不理想。但在低頻試驗中,由於取樣頻率不足與擷取延遲之影響較小,所以本文以影像應用於低頻電液伺服材料試驗機上,再結合自組織滑動模糊控制器,進行1Hz以下之動態之軌跡追蹤控制,分析在不同波形輸入下,電液材料試驗機的控制性能,並探討非接觸式CCD Camera 取代傳統LVDT 的可行性。
In the vision based control system, the lower frame per second and the delay of image processes are main reasons to degrade the control performance. These factors have no significant influence in the low frequency material testing. In experiments, vision based electro-hydraulic material testing machine is developed by self-organizing sliding mode fuzzy controller and to carry out dynamic tracking control under 1Hz. Square, sinusoidal and triangular waveforms are applied to analyze the control performance of this electro hydraulic testing machine, and then it will discuss the feasibility of non-contacted CCD camera to replace contacted sensors.
