| Abstract | A new Permanent Magnet Synchronous Motor (PMSM) Servo System is designed based on the dual-core composed of digital signal processor (DSP) and field programmable gate array (FPGA). The dual-core combined of DSP and FPGA achieves the control algorithm by assigning the tasks. The design of external circuit using FPGA simplifies the system structure and enhances the stability. DSP program with multi-interrupt drives the IPM module through pulse-width modulation (PWM) signals. The improved control methods of the three loops of PMSM servo system are achieved in interrupt program: the self-tuning control based on resistance and inductance observer is used in current loop, which ameliorate the following accuracy of current. In order to reduce the response overshoot, the speed is controlled by the integral-separated and limit-weaken PID controller. The feed-forward is added to the proportional position control to reduce the dynamic response error. The application on CNC lathe verifies the feasibility of the design of dual-core system and the control methods of the three loops. |

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.
