The key future is using a release pressure valve and a flow servo valve cooperated and a force sensor feedback to obtain hybrid pressure control. And using LabVIEW software designed fuzzy controller to obtain the hydraulic cylinder moving and output force precision control. Owing the hydraulic system can be accomplished small volume output high-power, such that it is used popularly to the industry. However, in the hydraulic system the oil is compressible and the system parameter variable can be affected by the oil temperature, the hydraulic servo system performances can be more affected by these disadvantages. We design a fuzzy controller to deal with this nonlinear and variable parameter hydraulic system to implement hydraulic cylinder position and force control performances. Through the constructed electro-hydraulic servo press machine system experimental testing, in the cases of step, multi-step, and sinusoidal force command inputs, the test results show that the proposed control scheme is capable of improving the tracking precision.
