| Abstract | PLL speed control systems can completely reject speed error and steady-state phase error for constant-speed inputs. Though it does not usually handle inputs including acceleration, the dual-loop scheme improves, as a feed-forward control system, rising time and phase error for acceleration input. However, since it is fundamentally a third-order PLL, it has slow rising up characteristics than speed feed-back, and cannot avoid over/undershoots. Nonetheless, the first loop has rapid rising up characteristics and no over/undershoot, since it is an ideal second-order PLL system. In this article, to solve the problem, we show a hybrid system of the dual-loop PLL and speed feed-forward/back. It has fast rising up characteristics and no over/undershoots thanks to the first and third PLL as F/V converter, which cannot be achieved in traditional PLL systems. |

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.
