Hydraulic Control System

An analysis is presented of a three-phase pulsating flow hydraulic control system. Such a system consists of five basic components – an alternator, transformers, rectifiers, a compensator and high and low pressure accumulators. In carrying out this analysis, it is assumed that there is no leakage, the fluid is incompressible, the transformer area ratio is unity and the transformers and check valves of the rectifier unit are symmetric. Some typical simulation and experimental results are included.

In this paper, the hydraulic control system design and dynamic analysis are considered in superior calculation efficiency based on Lagrangian method and fundamental laws for getting control algorithms to investigate about hydraulic system how to control hydraulic system and take hydraulic controller to the optimization. The systems built in dynamical parameters are associated hydraulic control system achieved with control parameters. And then, an interface is achieved. The relations between control parameters are obtained. The numerical tools are going to determine all kinematic parameters of bodies such as displacement, velocities, accelerations as well as reaction forces are responded. The AMESim and RecurDyn are used such Computer Aided Engineering (CAE) techniques to solve the numerical examples in this paper. Those examples will imply that the equation of motion based on Euler–Lagrange equation and characteristic effect of force is executable. Through results, we could achieve control improvement at different hydraulic systems.
