Applications Research on the Synchronization Control of Multi Hydraulic Cylinders of Dump Truck

摘要

In this article, a three-hydraulic-cylinders synchronization control model of the hydraulic system of a large dump truck is discussed and the proportional integral (PI) control is used for the hydraulic system. Simulation and performances comparison between the improved and unimproved system have been done by using MATLAB 7.10. To meet different practical engineering requirements, different control methods are designed and selected, aiming to the practical purpose.
