| Abstract | Giant Magnetostrictive Actuator (GMA) show strong stress-dependent hysteresis nonlinearity. A generalized Stress-Dependent Prandtl-Ishlinskii (GSDPI) model is formulated to characterize the stress-dependent effects of giant magnetostrictive actuator. In this model, a generalized play operator is proposed and integrated with stress-dependent weights to construct stress-dependent hysteresis model for GMA. Good agreements are shown between model simulation results and measured hysteresis loops. The analytical inversion of proposed model is given and employed in a control scheme, which combines inverse compensation with model reference control to control linear systems preceded by unknown stress-dependent hysteresis. By deriving the relationship between the tracking error of the system and parameters error of GSDPI, then an adaptive update law of parameters of model can be developed to ensure the tracking error asymptotically converges to zero. Simulation results validate the effectiveness of the proposed approach. |

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.
