摘要
提出采用短量程的传感器检测两个或多个长行程油缸的同步误差的相对检测法 ,与绝对位移检测比较 ,成本低 ,易安装 ,操作方便 ;建立了双缸同步补偿模拟实验系统 ,结合计算机技术实现了在线测控 ;提出模糊 -PID控制策略进行同步补偿控制 ,自行开发了相应的软件实现同步误差的补偿控制 ;为深海采矿长行程升沉补偿油缸的同步检测与控制提供了合理的实验数据。
s:A relative detecting method was put forward to detect the synchronous error of several long-stroke hydraulic by using short-stroke displacement sensor,which has the advantages of low cost,easy installing and convenience in operation compared with the absolute-detecting one.A synchronous model test system was established and the on-line detection and control was realized by utilizing computer technology.A strategy named as Fuzzy-PID control and a program developed for this system were used to accomplish the compensation of synchronous errors.The research presents an effective new method for detection and control of synchro-operation of hydraulic cylinders in deep-ocean mining heave compensation system.
