| Abstract | In view of the nonlinearity and parameter jump caused by the conversion of structure in rolling mill hydraulic servo system, a direct adaptive fuzzy controller based on sliding mode control is designed. Firstly, sliding mode function and control law are designed. Secondly, the direct adaptive fuzzy controller is constructed to approximate the total unknown terms in the control law, and the stability of the system is analyzed and proved through the Lyapunov function, we obtained the system is asymptotically stable. In addition, in this paper the optimal performance index is considered as the rule of switching control which can implement the effective switching among sub-models controller. Finally, the simulation results demonstrate that the designed controller can not only reduce the high frequency chattering effectively but also have good robustness for the system uncertainty and parameter perturbation. |

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.
