Variable speed hydraulic coupling research and development of intelligent electro-hydraulic control system

In recent years, the governor hydraulic coupling as a mature hydraulic control devices, has been in power, iron and steel, petrochemical, transportation, municipal sector and military equipment and other fields are widely used. Present in these systems, variable speed fluid couplings are mostly open-loop control system is running dynamic characteristics and transmission quality is not very good, thus affecting the overall system speed and energy saving effect. As science and technology and modern production development, especially the development of computer technology, variable speed  Hydraulic adapters  coupling speed closed-loop control functions began to receive attention, so that the servo mechanism relating to the control element, the control method of research has very practical significance. As a kind of hydraulic components, variable speed hydraulic coupling exists complicated dynamics, mathematical model is difficult to establish, the system adjusts the gain parameter uncertainty and serious nonlinear problems. In this article, the author in the servo mechanism, control method and controller implementations have made a new attempt, the use of intelligent control technology to achieve a variable speed hydraulic coupling speed closed-loop control, the control precision is improved, further increasing the governor energy savings, and therefore this topic research has certain practical significance and innovation
