| Abstract | Single-phase inverters are widely used in critical applications such as dynamic voltage restorer (DVR) and uninterrupted power supply (UPS) system. In such applications, the inverter must be capable of operating with low total harmonic distortion (THD) and quick transient response. This paper and its companion paper present two promising control methods based on neural networks. This paper presents a novel neural network-based adaptive controller for high performance single-phase inverters capable of maintaining a high quality output voltage with very low THD of less than 2% in the presence of unknown loads, either linear or nonlinear. In the proposed scheme, a voltage source inverter with its corresponding LC load-filter is controlled by an adaptive linear neuron (ADALINE) controller with only one sensor. The on-line adaptive learning algorithm developed in this paper guarantees steady-state controller stability. The principle, stability, robustness, and the special features of the control scheme are discussed. The scheme is simple to implement and has superior performance compared to other popular control strategies, such as the dead-beat controller. An important merit of the proposed control scheme is that it can be designed and implemented without knowing the exact parameters of the PWM inverter system. Simulation and experimental results are presented to verify the feasibility and performance of proposed approach. |

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.
