The hydraulic system controlled by digital valve have been described and analyzed in jacking feasibility and stability. What's more  it is inspected and verified that the adjustment of this system has high precision and quick response. 2009 IEEE.   高功率激光器自动准直技术研究 学位论文 作者:  李红 收藏  |  浏览/下载：37/0  |  提交时间：2018/12/26 高功率激光驱动器  High power laser facility  自动准直  Automatic alignment  图像处理  Image processing  自动控制  Automatic control  最小二值化  Binarization  耦合矩阵  Coupling matrix
