英文摘要： Appliable energy-saving technology has been one of the key problem in the domain where hydraulic system has been broadly used. For the hydraulic control system, it is predominately important to achieve the benefits of energy-saving techniques and keep the high control performamce that the hydraulic system inherently possessed. The aim of this project is to study the basic theory and the key techniques of the integrated control valve which can abtain high performance and energy saving. By integrating 5 individual control units, this valve can programmably control the meter-in and meter-out orifices independently. It is capable to control one individual orifice according to the work condition and eliminate the unwanted metering lose due to the mechanical link orifice in the conventional spool valve. Therefore, it can reduce the energy cost in hydraulic system. The topics that this project will investigate include: the integrated configuration and optimal design of the valve, the energy-saving principle and the control logics in different work conditions, the coordinate control strategy of the multiple control units to achieve high response performance, the stability analysis of the integrated valve, the adaptive theory for controlling the asymmetrical cylinder to abtain the same performance in both of its moving direction, the method to reduce the pressure impact when the acctuator change moving direction under the condition of high speed and large inertia, the manufacturing techniques of the key components of the valve. It is potential to find out a new way for improving the efficiency of the hydraulic system by using this valve. As a result, this project will provide the support of industry application and relevent techniques for the integrated high performance and energy saving valve.
