| Abstract | To improve the equality of continuous casting billet, synchronization control is investigated for continuous casting mold driven by dual-cylinder electro-hydraulic servo systems (EHSS) in this paper. A second-order super twisting sliding mode controller is developed for each cylinder EHSS, in which cross-coupled errors are employed to construct the sliding mode surfaces, which guarantee that trajectory tracking errors of each cylinder EHSS and the synchronization error can rapidly converge to zero in finite time even in presence of the parameter uncertainties and external disturbances. Furthermore, to reduce the chartering caused by the discontinuous control law of sliding mode control, adaptive gains are employed during the sliding mode controller design. Thus, an adaptive sliding surface cross-coupled synchronization controller is presented by employing Lyapunov stability theorems. Simulation results in a model obtained from a real continuous casting mold demonstrate the effectiveness of the method. |

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.
