The other lies in the imported electro - hydraulic controller itself . being a general product , the imported control doesn ’ t work well in particular working conditions in china 本文密切结合湖南省科技攻关重点项目进行研究,围绕“汽车起重机电液比例控制系统”的开发做了大量的工作。
This paper introduced the principle and realization method as well as control characterristics of the electrohydraulic servo proportional control system of the vrc robot . its nationality are also been discussed 介绍了vrc机器人电液伺服/比例控制系统的原理、实现方法与控制特点,为该技术国产化进行了理论探讨
Expect for the design of the amplifier , the emphases is to test the static state and dynamic characteristic of the control system and provide a great deal reference data so that the system can work well 论文中除了对放大器的电路做了介绍外,重点是对放大器在比例控制系统的运行中做了大量的静态、动态参数测试,为比例电磁阀的良好工作提供了一系列的参考数据。
One reason is that poor of technical level , most civil manufacturers ’ products are based on the imported electro - hydraulic proportional controller which is act as the core , as a result , the cost become higher and lost the advantage of lower cost 在我国由于起步晚,技术水平低,汽车起重机生产厂商往往需要从国外引进电液比例控制系统核心控制器,以提升自身产品的竞争力。
The main work of the thesis is as follows : 1 . the feasibility of the scheme in engineering is discussed by means of analyzing the strategy of position control system . 2 . the mathematical model of the position control system is established and analyzed in theory 论文以研配压机位置控制系统的研究为题目,其主要工作如下: ?对1000kn双侧翻转研配压机进行了简介,对电液比例控制系统进行了分析。
