Abstract | A new approach for real time digital feedback control of PWM inverter is proposed, in which an ideal instantaneous deadbeat control is realized without any sampling compensation method using FPGA based hardware controller. Deadbeat control ensures the state variables matches at each sampling instants for every sampling period. Generally this kind of control system is realized based on DSP based software controller, so some kind of sampling compensation technique is necessary because the state variables at kth sampling instant cannot be used for control outputs at kth control period. In this paper, a novel approach to realize the ideal dead-beat control using FPGA based hardware controller is proposed. The FPGA based hardware controller enables to realize almost ideal real time digital feedback controller because of its capability to realize very fast calculation of the control method with is a few /spl mu/ second. As the result, the state variables at kth sampling instant can be used for the control output at kth sampling interval, the real time digital feedback control can be realized without any sampling compensation. From the view point of UPS applications, the advantages and the disadvantages are discussed through simulations and experiments, the superiority of the proposed control law is verified. |

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.
