Dynamic parameters characterizing proportional hydraulic components are essential factors affecting the performance of the construction machinery automatic control system. Knowledge of these parameters is inevitable in modelling the automatically controlled hydraulic power systems as well as designing and analysing the control algorithms. This article presents a methodology of assessing the dynamic parameters of selected components being part of digitally controlled hydraulic power system. The analysed system comprised a typical for mobile hydraulics applications PVG32 proportional directional control valve (DCV) and a variable displacement piston pump. The control system utilised an MC088 PLC controller with specifically prepared and configured software. The measuring system was based on CANbus, which, combined with the PLC used, allowed for flexible configuration of the sensor variables and logging both analogue and digital signals. Among others, the DCV characteristics, the response to step and sinusoidal inputs and DCV hysteresis were examined. The goal was to gather the data required for system modelling and to assess the importance and influence of the investigated parameters onto the model being created.
