Abstract | This paper considers anti-windup design for linear systems subject to actuator saturation. Three anti-windup gains are designed for activations immediately at the occurrence actuator saturation, after the saturation has reached a certain level and in anticipation of the occurrence of saturation, respectively. The design is based on the minimization of ℒ2 gain from the disturbance to the controlled output of the resulting closed-loop system. Traditional anti-windup scheme involves a single anti-windup loop for immediate activation. A recent innovation is to design a single anti-windup loop for delayed or anticipatory activation, as well as to design two anti-windup gains, one for immediate activation and one for delayed activation. Our design of three anti-windup gains for three different activations is shown through simulation to lead to significant further performance improvement over the previous activation schemes. |

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.
