Abstract | To make the control strategy design concise and easy to practical application. Based on a linear three-phase shunt Active Power Filter (APF) model, the Linear Quadratic Regulator (LQR) is utilized to obtain the optimal state feedback control rate. To improve the stable performance of the system, the optimal state feedback control combines with an output integral feedback loop to construct an optimal Proprotional-Integral (PI) regulator. Additionally, the differences between those two control strategies are analyzed in detail. Simulation results are demonstrated to verify that those two control strategies can be applied in three-phase shunt active power filter well and own fast response. Moreover, the results show that in suppression of low frequency harmonics, the performance of the optimal PI regulator is better than the optimal state feedback controller. |

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.
