Abstract | In this paper, the dual closed-loop vector control of the three-phase voltage source pulse-width modulated (PWM) rectifier based on fractional-order controller is studied. The classical proportional integral (PI) controller is used in the inner current loop. The feed-forward decoupling control method is established to regulate active currents and reactive currents. In this way, a power factor of the system is close to one. The fractional-order controller is used in the outer voltage loop to stable the direct current (DC) output voltage. It can enhance the robustness of the system, weaken impacts from the load disturbance and the grid disturbance to the output characteristics of the system, and ensure that the DC voltage remains stable with the parameters changing. Correction method which combining the frequency-domain analysis and flat phase condition is used to tuning the fractional-order controller. Through theoretical analysis and simulation research, we proved that the method enhances the immunity and robustness of the system. With the virtue of faster respond and less overshoot, it can get better control effectiveness. |

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.
