| Abstract | This paper addresses the problem of selecting an actuator so that the performance degradation due to its saturation is sufficiently small. The following scenario is considered. The plant is assumed to be linear and the problem of colored noise disturbance rejection is addressed. The controller is designed using a linear technique (for instance, PID, LQG, etc). This controller is to be implemented with a saturating actuator. How large should the level of saturation be so that the performance will not degrade too much? We provide an answer to this question (in terms of the Nyquist plot of the loop gain) for any desired level of degradation. In addition, the following rule-of-thumb is established: To guarantee less than 10% of performance degradation, the level of actuator saturation should be at least twice larger than the standard deviation of the signal at the controller output in linear design. |

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.
