Abstract | Fault diagnosis in pneumatic actuators is a very difficult task due to the inherent high nonlinearity and uncertainty. Developing models of nonlinear systems with adaptive network-based fuzzy inference systems (ANFISs) has recently received attention. Models that are built upon ANFISs overcome the disadvantages of ordinary fuzzy modeling and can be very suitable for generalized modeling of nonlinear plants. We set up a group of ANFIS models which are relatively common in practice, corresponding to various situations of a pneumatic actuator, including normal, low and high supply pressure. Considering the advantage that a learning vector quantization (LVQ) neural network has a powerful ability to classification, we then utilize a LVQ neural network as a fault diagnosis scheme by abstracting the data of ANFIS models as the input vectors for nonlinear plants. The effectiveness is demonstrated via experiments on a pneumatic actuator. |

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.
