| Abstract | This paper presents a novel periodic learning disturbance observer(PLDOB) based controller that considers a long-term instability problem to achieve high precision position control in permanent magnet linear synchronous motor (PMLSM) motion systems under repetitive motion conditions. In the proposed scheme, an initial condition for PLDOB, which is the learning law in the proposed controller, is designed by a linear disturbance observer (DOB) due to an advantage that the learning law is designed directly from a point of a view of the disturbance, unlike ILC and RC. The use of the initial condition in the proposed scheme improves the learning speed to minimize tracking errors and guarantees the stability of the overall system at fast learning speed. In the proposed controller, no mathematical models are required to compensate for the dominant disturbances such as friction forces, force ripples, and model parametric errors in the PMLSM motion system, and the lumped disturbance is attenuated by PLDOB. The weaknesses induced by the use of Q-filter of DOB, such as the phase lag and limited frequency range for the estimated disturbance, are compensated, and it improves the transient performance and tracking performance. Also, theoretical analysis for the long-term instability problem is performed |

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.
