| Abstract | This paper presents a comparative study between the classical (Hysteresis and Proportional-Integral using PWM technique) and Predictive controllers for three-phase voltage source inverter. The hysteresis controller provides excellent dynamic performance, whereas the Proportional-Integral controller provides instantaneous current control and wave shaping, fixed inverter switching frequency resulting in only known harmonics. Predictive control method uses the discrete - time model of the system to predict the future value of the load current for all possible voltage vectors generated by the inverter. The voltage vector which minimizes the quality function is selected. The quality function used in this work evaluates the current error at the next sampling time. A comparison has been made in terms of THD level at the three phase load current. The simulation study has been carried out with the help of MATLAB Simulink environment and the performance of such controllers has been observed during load variations. The results shows that the predictive controls very effectively the load current and performs very well compared with the classical current controllers. |

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.
