| Abstract | In actual control systems, many types of restrictions or nonlinearities exist. For example, owing to nonlinearities in the actuators or sensors, the controller may not be applicable in some practical situations. Such a nonlinearity is amplitude saturation in actuators. Although it may sometimes be ignored, failure to consider actuator saturation may severely degrade the performance of a closed-loop system, and even lead to instability. On the other hand, limiting the controller gain to avoid saturation sacrifices control effort, and may lead to loss of performance. Many approaches have been tired in order to overcome these undesirable problems, and some good results have been obtained. The saturation has been replaced with a gain which is calculated as a function of the variance of the signal at its inputs. Based on this assumption, some attractive control theories have been introduced. Here, we introduce a useful anti-wind-up control system. In other words, the control system proposed has a very simple design process and can guarantee good control performance, as it is based on the assumption that the saturation is replaced with a varying gain. The validity of the proposed control system will be shown by comparing some simulation 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.

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.
