| Abstract | Kalman filter is a well-known technique for optimal state estimation and is widely used for its applicability in different fields. Different derivatives of Kalman filter have been proposed in the past to consider the non-linear aspects of system and measurement model. However, these estimation techniques require precise tuning of process and measurement noise covariance matrices for a given system. This tuning is not only a non-trivial process, but also requires engineering intuition and huge number of Monte Carlo Simulations of the system noise, which at times takes days to freeze. In this paper, a Human Opinion Dynamics (HOD) based optimization of Extended Kalman Filter (EKF) has been proposed for obtaining the tuning parameters. Using these tuning parameters, EKF simulations are carried out for a permanent magnet synchronous motor system model, and thus obtained state estimates are compared with the state estimates obtained from Particle Swarm Optimization (PSO) based tuning method. The simulation results depicts HOD based technique being comparable with the PSO based technique on accuracy grounds and out performs in terms of convergence and ease of implementation. |

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.
