Interfacing Hydraulic Systems and Microcomputer Controls

The intent of this paper is to provide hydraulic and electronic technologists an overview of the load-control-power loop intrinsic to hybrid microcomputer-hydraulic systems. This paper shows the relationships between machine loads, load variables,-interfacing loads with control systems by means of sensors/transducers; how to achieve sensor compatibility with the microcomputer; how signals are passed to and from the control computer; interfacing analog and digital signals with fluid power control components; fluid power actuator-load interaction.
