This paper regards to design and examination of electrohydraulic control systems with separate metering edges for mobile applications. Although the idea of individual metering has existed for some time; this promising technology has yet to be applied in field. One reason for the missing prevalence is the lack of understanding regarding the complex control requirements. Furthermore; expected additional expenses regarding components such as valves and transducers hinder the acceptance. This work outlines a systematic analysis of possible circuit concepts. The obtained solution space contains a large number of elements that must be evaluated based on functional and economical criteria. Therefore; it is advantageous to divide the control system into its functional fractions. The clear distinction of the functional fractions enables a systematization of the different drive and control tasks; which then can be combined freely. The selection of appropriate control signals can be supported by the usage of a multivariable system modeling approach. Physical interactions; inherent to electrohydraulic systems; have a strong impact on the behavior of the control loops. By analyzing the coupling elements; conclusions regarding control concepts and structures can be drawn
