| Abstract | This work presents a model-free predictive current control (MFPCC) that is suitable for a voltage source inverter with a decoupled three-phase load. With this method, the load currents and the load current differences are available to predict the future load currents associated with eight possible switching states, generated by the inverter. Unlike model-based predictive current control (MBPCC), the proposed method is not based on any discrete model of the system. Clearly, it is only based on detecting the load currents and the current differences. In other words, it does not require any parameter of the system, such as resistance, inductance, or back-EMF. In addition, the proposed MFPCC only needs twice current measurements in each sampling interval. Similar to the MBPCC that the optimum switching state is chosen by minimizing a cost function, the MFPCC also undertakes this optimization process. The proposed MFPCC ensures that the load currents tracks the reference ones with high accuracy reducing the transient and steady-state errors. Using $MATLAB^{®}$ software, comparative simulations of the above two methods can be obtained to show and validate the feasibility and correctness of the proposed strategy. |

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.
