Abstract
As part of the study involving the design and implementation of axial piston pump control systems, an accurate, dynamic model of a axial piston pump is required. In this thesis, the complete derivation of such a model is presented. The derivation is performed symbolically, using general geometrical coordinates and parameters of a typical axial piston pump, rather than specific values. Therefore, the developed model should be applicable to other types of axial piston pumps with similar configurations.
The developed model is expressed by a set of highly nonlinear mathematical equations, these equations being functions of pump parameters and operating conditions. When the specific values of these various parameters were substituted into the describing equations, it was found, for the pump used in this study, that the model could be simplified to a set of linear expressions. In addition, the experimental results indicate that the developed model accurately predicts the dynamic response of a particular pump - a Vickers PVB5 axial piston pump.
