本文介绍了三块双层升降舞台液压系统的设计原理,论述了采用计算机和电液比例调速阀控制同步运动的控制原理。实测结果表明:同步运动平稳,同步误差小于0.2%。
This paper introduces the design principle of three double stage hydraulic system, discusses the control principle of using computer and electro-hydraulic proportional valve to control synchronous motion. The measured results show that the synchronous motion is stable and the error of synchronization is less than 0.2%.
