WATER HYDRAULIC SYSTEM FOR HIGH SPEED CYLINDER DRNE

The Position Control of the Hydraulic Cylinder Controlled by the High-Speed On-Off Valve

This paper aims to research the position control of the hydraulic cylinder controlled by the highspeed on-off valve to realize the precise position control. A compound algorithm of proportional integral & speed feedforwarddisplacement feedback is put forward based on the research on the relationship between the duty ratio and the past flow for the high speed on-off valve. The speed feedforwardd...

Monitoring the Condition of Loaded Modern Water Hydraulic Axial Piston Motor and Cylinder

Recent advancement in technology has produced materials that can withstand highly corrosive environment and lubrication-free materials for water hydraulic components. With precision machining becoming possible, very close tolerances can now be achieved to reduce internal leakage due to the low viscosity of water. Many industries are slowly but steadily turning to water hydraulic systems to repl...

End-System Optimizations for High-Speed TCP

Modern TCP implementations are capable of very high point-to-point bandwidths. Delivered performance on the fastest networks is often limited by the sending and receiving hosts, rather than by the network hardware or the TCP protocol implementation itself. In this case, systems can achieve higher bandwidth by reducing host overheads through a variety of optimizations above and below the TCP pro...
