| Abstract | This paper presents a hardware realization of an adaptive fuzzy controller (AFC) for a permanent-magnet linear synchronous motor (PMLSM) drive system based on the field-programmable gate-array (FPGA) technology. First, a mathematics model of the PMLSM drive is defined; then, to increase the performance of the PMLSM drive system, an AFC constructed by a fuzzy basis function and a parameter-adjustable mechanism is applied to the position-control loop of the PMLSM drive system to cope with the effect of the system dynamic uncertainty and the external load. A point-to-point (PTP) motion trajectory designed with the trapezoidal velocity profile is considered to smooth the move of the PMLSM at the start and stop conditions. Second, a finite-state machine (FSM) joined by a multiplier, an adder, a lookup table, and some comparators and registers is presented to model the overall AFC, and a VHSIC hardware description language is adopted to describe the circuit of the FSM. In addition, a Nios II embedded processor is used to implement the function of the PTP motion-trajectory algorithm by software. Finally, an experimental system is established to verify the effectiveness of the proposed FPGA-based AFC and the PTP motion-control system, and some experimental results are confirmed theoretically. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
