| Abstract | The establishment and control for a switched-reluctance generator (SRG) are presented in this paper. First, the switching behavior and the DC-link ripple characteristics of a SRG are studied. Accordingly, its circuit and control models are established. And the power circuit components are properly designed to minimize the DC-link voltage ripples caused by commutation and pulsewidth modulation switching. Second, the quantitative voltage feedback control of the SRG system considering the effects of voltage ripples is made. In this issue, a unified approach is developed to estimate the plant dynamic model parameters from measurements. Then conversely, the feedback controller is designed according to the prescribed regulation voltage control specifications. Third, a dynamic commutation shift controller (DSC) is devised to enhance the voltage control performance of a SRG. As the voltage feedback control is failed when winding current becomes single-pulse mode, the proposed DSC is actuated automatically. The turn-on and turn-off angles are dynamically and automatically shifted to assist voltage feedback regulation control. More stable and better regulation control performance can be obtained. Finally, the energy conversion efficiency improvement via static commutation shift under static operation is evaluated experimentally. Theoretical bases of the proposed control approaches are derived, and their effectiveness is demonstrated by some simulation and measured results. |

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.
