| Abstract | In path tracking design, different methods were developed. In previous works we have presented a method based on fractional differentiation in order to reduce overshoots on the actuator output. It allows the generation of an optimal movement reference-input leading to a minimum path completion time, taking into account the maximum velocity, acceleration and jerk, and the bandwidth of the closed-loop on which the input is applied. Different strategies were developed. In this paper, three methods taking into account the jerk limitation are compared. A comparison with classical input shaper approach is also done. The two first methods, based on fractional differentiation, are used through a Davidson-Cole prefilter with acceleration or jerk bang bang input, to ensure continuity on acceleration and jerk signals on the actuator. The third approach is based on preshaper synthesis with jerk limited input; the shaped input is obtained by convolving desired input with an impulse sequence. The synthesis methodologies of the different methods are studied. Performances are compared on an example, in both frequency and time domains. |

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.
