| Abstract | This paper proposes an improved particle swarm optimization (IPSO) algorithm for IIR system identification problem. IPSO adopts three novel steps as follows: The population initialization step is based on golden ratio, which is beneficial for improving the quality of candidate solutions. In velocity updating step, all particles use different inertia weights, which is helpful to preserve the balance between global search and local search. Moreover, the proposed algorithm incorporates normal distribution to disturb the global best particle, which enhances its capacity of escaping from the local optimums. These properties of IPSO make it better suited for IIR system identification problems. IPSO is applied to twelve instances, and experimental results demonstrate that IPSO is capable of obtaining the best objective function values in all cases. Compared with the other four PSO approaches, it has better convergence and reliability which clearly points out its better performance in search accuracy. |

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.
