| Abstract | This paper investigates the dynamic performance of bioethanol production process. The process is simulated by an experimentally validated model in the literature. The analysis of the open loop system revealed that the maximum productivity occurred at a moderate ethanol production and substrate consumption. Improvement of the process productivity beyond the maximum value is sought through periodic input forcing. Rectangular pulses were used to simulate the periodic input function because they are suitable for discrete control systems. The parameters of the rectangular pulse such as period, amplitude and central value were designed using numerical optimization. Forcing the optimized cycling input into the process revealed substantial increment of the ethanol production and substrate consumption. However, the obtained enhancement of productivity is considered marginal when compared to the existing maximum productivity. On the other hand, enrichment of productivity is considered reasonable when compared to that obtained when the process operates at steady state using the average value for the input periodic function. |

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.
