Research of Hydraulic Cylinders Dynamic Characteristic and Synchrocontrol on Horizontal Pipes Connector in Deep Sea

Abstract:

The electro-hydraulic position-servo synchronization system of horizontal pipes connector was designed in order to connect two pipes in deep sea and make sure the journey of synchronization hydro-cylinders in the hydraulic system is less than 2 mm.Its transfer function of symmetric servo controlling oil-cylinder electro-hydraulic servo system were derived . Simulation analysis of its dynamic characteristic was done, and PID controller was applied on the system to regulate two hydraulic cylinder synchronization controls. In the end ,when the proportionality coefficient is Kp=0.55,integral coefficient is Ki=60,differential coefficient is Kd=0,the error of synchronic displacement was less than 0.5 mm, that achieved the request of the control system.
