Hydraulic Control System

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.

Hydraulic Control System

A low speed hydraulic control system applying to 3.15MN forging press isdesigned for isothermal forging processes. Based on the hydraulic theory andthe system structure, both the mathematical model and the simulation model ofthe hydraulic press are established with its features discussed. PID controlmethod is adopted and genetic algorithm is used to automatically tune theparameters of the controller to deal with nonlinearity and time-variant of thecontrolled plant. Co-simulation of the control system and hydraulic system isestablished to verify the feasibility of the design. It is proved by anisothermal forging of a turbine disc that the system has good performances andcan achieve an ultra speed control in the end.

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.
