| Abstract | This paper presents the design and architecture implementation of a digital position control IC for permanent magnet synchronous motors (PMSMs) with sinusoidal flux distribution using linear Hall sensors for low-cost motion control applications. The absolute rotor position is calculated from the measured Hall sensor signals and a speed estimator is devised to generate speed feedback for the servo loop compensator. The developed digital servo control IC for PMSM motors with linear Hall sensors consists of three major control blocks: a servo loop controller, a position and speed estimator, and a field-oriented torque controller. The accuracy of positioning control resolution can be improved by a position error compensation table via external position calibration. All the control blocks are realized by using digital circuitry with configurable and reusable intellecture property (IP) blocks. Experiment results are presented to verify the performance and feasibility of the proposed IC. |

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.
