Abstract

There had been developed the mathematical model and conducted researches on the characteristics of the proportional directional control valve with electrohydraulic controlling, namely, the dependence of the main spool position on the servo spool displacement, pressure drop across the main spool edge and on the slope angle of the main spool working edge. As a result, the essential nonlinearities of the control system have been exposed both in static and dynamic operation modes. These nonlinearities can be reduced by means of selecting appropriate values for the slope angle of the main spool working edge.
