Abstract | The hydraulic system of flash welding machine and loading system has nonlinearity, force coupling arising from mechanical structure and time-varying parameters and demands huge upset force, respond with high-speed and two loading hydraulic cylinder move and load synchronously while the cylinders sharing the even load. It's difficult to model mathematics accurately. So we designed the control scheme of model-free adaptive and the controller of model-free adaptive. By simulation, we succeeded in solving the problem that it is difficult to model mathematics accurately. Simulation result show that the error of dynamic pressure synchronization is little and that the error is stable. The control effect of upset force servo is good and the output of upset force servo is stable. The control scheme is feasible. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
