Abstract | For the characteristic of permanent magnet linear synchronous motor (PMLSM )that has no middle transmission links--the load connects to the motor active cell directly, the load resistance, the quality changes and the external disturbances directly influence the performances of the servo system, this paper uses a programme of self-tuning zero phase error tracking control (ZPETC ). The quality of active cell, viscous friction coefficient and load resistance are identified on-line using recursive extended least square (RELS )with amnestic factor. Then ZPETC can self-tune according to the identified parameters. This can make servo system still have good tracking performances when the parameters are changed. A load observer is designed to overcome bad effects of load variation. To ensure the accuracy of load observer, the quality of active cell, viscous friction coefficient and load resistance have been identified are used to update the parameters of the system, so it can improve ability to resistance disturbances of the servo system varied. The simulation results show that the method enhances the fast tracking performance, and has a stronger robustness to parametric variations and disturbances. |

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.
