Abstract | This study presents a newly-designed nonlinear decoupled control for a linear induction motor (LIM) servo drive. First, an ideal feedback linearization control (IFLC) system is adopted to decouple the thrust force and the flux amplitude of the LIM. However, the control performance of the LIM is influenced seriously by system uncertainties. Therefore, to increase the robustness of the LIM drive for high-performance applications, a sliding-mode feedback linearization control (SMFLC) system, that comprises a sliding-mode flux controller and a sliding-mode position controller, is proposed to decouple the thrust force and the flux amplitude of the LIM. The control laws of the SMFLC system are derived in the sense of Lyapunov stability theorem such that the asymptotic stability of the control system can be guaranteed under the occurrence of system uncertainties. Moreover, to relax the requirement of the secondary flux in the SMFLC system, an adaptive flux observer is proposed to estimate the secondary flux considering all possible uncertainty in practical applications. In addition, the effectiveness of the proposed control scheme is verified by some simulated results. |

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.
