| Abstract | This paper presents the use of neural networks and a genetic algorithm within a model-based friction compensation scheme in a closed-loop robotic system. Unlike previous works which concentrate on using a single type of neural network to model friction function, three types of neural network, namely a multilayer perceptron, a radial-basis function network and a modular network, are used in the modelling task. The genetic algorithm is then used to find the optimal combination between the radial-basis function network and the multilayer perceptron and that between the radial-basis function network and the modular network. The simulation results indicate that the genetic algorithm has successfully found the combinations of the neural networks which results in a better compensation performance than using only one type of neural network. As a result of using both neural networks and a genetic algorithm in this application, an idea of a task hybridisation between neural networks and a genetic algorithm for use in a control system is also effectively demonstrated. |

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.
