| Abstract | Input shaper is a pre-filter, designed to suppress residual vibration of flexible systems. The input shaper can be placed inside the feedback loop, in front of the flexible plant, to avoid exciting the plant vibratory modes. The performance of this so-called closed-loop signal shaping is limited due to the time delay brought about by the input shaper. The input shaper has more time delay when the plant mode parameters are uncertain. In this paper, an inner-loop controller based on the quantitative feedback theory is designed to match the uncertain flexible plant to a reference model. As a result, the input shaper needs not be robust, and the time delay is reduced. Other benefits include shorter input shaper length, increasing controller bandwidth, applicable to time-varying plant, and reducing cost of feedback. Simulation and experiment have confirmed the effectiveness of the newly proposed technique. |

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.
