摘要

在基于视觉的控制系统中，较低的每秒帧数和图像处理的延迟是降低控制性能的主要原因。这些因素对低频材料试验影响不显著。在实验中，采用自组织滑模模糊控制器开发了基于视觉的电液材料试验机，实现了1Hz频率下的动态跟踪控制。采用方形波形、正弦波形和三角形波形分析了该电液试验机的控制性能，探讨了非接触式CCD相机替代接触式传感器的可行性。

A vision based low-frequency electro-hydraulic fatigue testing machine

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.
