| Abstract | In this paper, we show that a mathematical relationship exists between the multiple-process soft switching (MPSS) algorithm and an interacting multiple-model (IMM) algorithm. Assuming that each model transition probability is equally likely, the constraints imposed on the mixing and fusion gains in the IMM algorithm are equivalent to those in the MPSS algorithm. Thus, the constraints derived from a probabilistic approach can be reduced to those obtained via a deterministic approach. Unlike the MPSS algorithm with the aid of an additional constraint, the proposed IMM algorithm uses the real-time information of the innovations and their covariances to select filter gains between 0 and 1. The MPSS and the proposed IMM algorithms are applied to tracking a maneuvering target. Simulation results show that the latter has a better position tracking capability than the former when the measurement noise is small or moderate; however, both have similar performance in position tracking when the measurement noise is large. In view of the simulation results, more insights on the performance of MPSS, the proposed IMM and IMM algorithms are provided in the paper. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
