| Abstract | Functional neuromuscular stimulation (FNS) is one of new approaches in modern rehabilitation engineering. In this article, the adaptive iterative learning control algorithm is investigated for FNS multi-join limb motion system. At first, the FNS control system and its basic principles are given. Then, according to the nonlinear phenomena of the limb muscles, the discrete time-varying nonlinear model with undetermined and unexpected perturbations is defined, and a general expression based on the adaptive iteration learning control algorithm is developed, and the control algorithm structure block diagram is presented. Finally, based on multi-purpose FNS limb motion control system, the clinical experiments on motion trajectory-following of elbow flexion and wrist flexion were conducted by means of the adaptive iteration learning control algorithm and conventional control algorithm. The results of clinical studies have demonstrated that the adaptive iteration learning in control algorithm is more suitable for the improvement of the dynamic response characteristics and the stabilization of limb motion than conventional control algorithm. Furthermore, the stimulated patients have not any bad physiological reactions because the output electrical stimulation pulses generated by the adaptive iteration learning control algorithm vary gently. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
