Independent Metering Electro-Hydraulic Control System

This book shows an independent metering electro-hydraulic control system involving its flexible hardware layouts, complex software control, representative products and applications. The book includes one chapter introducing the background and motivation of the independent metering electro-hydraulic control system. It also includes one chapter to summarize various hardware layouts involving the utilized hydraulic components and circuits, as well as analyze their advantages and disadvantages. It emphatically consists of four chapters demonstrating the detailed multivariable control strategies from three levels: load, valve and pump, together with fault-tolerant control under the fault condition. It includes a last chapter, in which products of independent metering control valve and their applications in some typical heavy-duty mobile machinery are collective works of reviews illustrative of recent advances. This book is interesting and useful to a wide readership in thevarious fields of fluid power transmission and control.

Provides a detailed description of techniques and applications of independent metering electro-hydraulic control system Discusses research advanced of both piloted and main stages hardware layout Describes multi-mode switching control logics and corresponding algorithms of 3 levels containing load, valve, and pump
