Variable-displacement piston pumps (VDPP) offer control options based on pressure, flow, horsepower, or a combination of those parameters. Paul Badowski, from Cross Co., reviews the basic types of ...

Abstract: In this work robust control methods are used to design and analyze control systems for a variable-displacement hydraulic pump. More accurate uncertainty descriptions are derived by using an ...

ABSTRACT: Nutrient application systems are designed to apply a relatively uniform amount of a fertilizer to agricultural fields. However, considerable variation in soil texture and other ...

Abstract: Electro-hydraulic actuator(EHA) with variable rotational speed fixed displacement pump or fixed rotational speed variable displacement pump flow regulation has been very common. But these ...
