Article Preview

A relative detecting method is proposed to detect the synchronous error of several long stroke hydraulic cylinders by using a short stroke displacement sensor, which has the advantages of low cost, easy to install and convenient in operation compared with an absolute detecting one. A synchronous model test system is established and on-line detection and control is realized by utilizing computer technology. A strategy named as Fuzzy-PID control and a program developed for this system are used for compensation of the synchronous errors. An effective new method for detection and control of synchro operation of hydraulic cylinders is presented for a deep ocean mining heave compensation system.
