| Abstract | In this paper, we examine the effect of parasitic delays and lags on the stability of a string of vehicles equipped with adaptive cruise control (ACC) system which is employed a constant time headway (CTH) policy. The control law of the ACC system is based on a simpler model of the vehicle that does not ignore the parasitic delays and lags. The main result of this paper is that string stability can be guaranteed if the constant time headway h, is at least twice the sum of the parasitic delays Delta, and the parasitic lags tau, that is, h > 2 (Delta+tau). This result extends and generalizes the earlier results of Darbha by considering parasitic delays and lags and provides a practical direction for ACC system design and implementation from the viewpoint of robustness to parasitic delays and lags. |

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.
