从ＢＯＳＣＨ电液控制系统看国外技术发展方向余纪纲电液控制系统作为一种精密、有效的控制方式，已经有５０年左右的历史。在传统的电液控制系统里，核心元件是伺服阀，其动静态特性直接关系着受控系统性能的优劣。经历了数十年使用经验的积累，以及现代加工手段的进步...
From the BOSCH electro-hydraulic control system to look at the direction of foreign technology Yu Jigang Electro-hydraulic control system as a sophisticated and effective control methods, about 50 years of history. In the traditional electro-hydraulic control system, the core component is a servo valve, the static and dynamic characteristics of the performance of the controlled system is directly related to the pros and cons. After decades of experience in the use of accumulation, as well as the progress of modern processing methods ...
