Model predictive control design for axial-piston pump
IOP Conference Series: Earth and Environmental ScienceAbstract The article presents model predictive control (MPC) design of the displacement volume control of a variable displacement axial-piston pump. The pump is intended for application in open loop circuit hydraulic drive system. The authors are developed a real-time control system contains two basic components: an electro-hydraulic ...

Experimental investigation in axial piston pumps barrel dynamics
, 2009 It is known that an axial piston pump barrel experiences small oscillations due to forces acting over it. Cavitation als o occurs in many cases, damaging the plate and barrel sliding surfaces and therefore reducing the volumetric and overall efficiency of the pump.
