| Abstract | Turboshaft control systems are designed to keep the stability of helicopter, which requires that the powerturbine rotor speed remains constant. Furthermore, the power provided by each engine on the same aircraft is probably not equal if the control system provides the same fuel to each one. In this paper, a control loop aiming at balancing engine output torque and load system demand torque was added in the traditional speed-control system. Then a new structure of PI controller was developed with three control loops. Besides, the research showed this control system could be improved to keep the output torque of each engine equal to deal with the different performance degradations of different engines. Finally, the parameters of PI controllers in this control system were achieved by constructing and solving linear matrix inequality constraints based on the theory of regional pole placement for closed-loop system. |

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.
