| Abstract | Piezoelectric actuator is widely used in precision positioning mechanism for the advantages of ultra-high resolution, easy miniaturization, and rapid dynamic performance. But piezoelectricity material has nonlinear hysteresis effect. Due to this characteristic, accurate tracking is difficult to be achieved. In this paper, a model for piezoelectric actuator with hysteretic nonlinear model is developed. Also to improve the performance of piezoactuator, two control algorithms, adaptive PID control based on RBF neural network and ANFIS controller based on RBF neural network identification, are proposed. In both controllers, an identification algorithm is used to adjust timely the weights and coefficients of the controllers. Then simulation results of these algorithms are compared with together. The results show that an average error of ANFIS controller and a PID-RBF is close together; however, ANFIS controller is capable to reduce the effect of hysteresis better than the PID-RBF controller. |

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.
