System modeling and control design of a two-stage metering poppet-valve system
… to create an independent metering function for a hydraulic circuit. First, this system is modeled as a nonlinear open-loop model as well as a linear one. The completely linear form of the flow force acting on the poppet head is derived from simplified Navier-Stokes Equations. Second, four control …

A Tractor Mounted Device Used for Comparison of In-Situ Soil Bearing Capacity Between Two Tillage Regimes
… tests and a probe for cone penetrometer tests. A hydraulic cylinder powered by the tractor's auxiliary hydraulic circuit forced the footing or cone penetrometer into the soil. Load cells were used to measure bearing plate and cone penetrometer loads. A linear potentiometer was used to measure …

A novel hydromechatronics system towards: micro-independent metering.
… into the development of an existing hydraulic control system known as Independent Metering towards Micro-Independent Metering (MIM). The Independent Metering system uses a different configuration of the connection between the main elements of the hydraulic systems when compared to a …
