Structural design of independent metering control systems

Abstract

This contribution aims to develop and investigate new electro-hydraulic control systems using independent control edges. Based on a systematic elaboration and analysis of the possible solution space, both the supply and the valve-structures and in particular their interaction in form of control concept are subject of investigation. As a result, the synthesis of the drive system yields in structures, which are characterized by a simple valve design and a low component effort (proportional valves, sensors, magnets). The system behaviour can be further improved by examining the limits and possibilities of operating and control strategies. Exemplary results from simulations are used to clarify the correlations.
