【Abstract】 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.更多还原
