| Abstract | Modern aircrafts are equipped with more control effectors to enhance the reliability and survivability. Control allocation is used to deliver the virtual control moments to redundant control effectors. Due to the physical constrains and aerodynamic considerations, each control effector has some constrains and the control allocation becomes more complicated. A new control allocation algorithm based on weighted pseudo-inverse is proposed in this paper. Weighted pseudo-inverse is a control allocation method with easy structure and high computational efficiency, but it could not give out the optimal result. Genetic algorithm is a randomized search algorithm. In this paper, it will be used to optimize the weighting matrix to achieve maximum attainable moment set. To enhance the performance of the algorithm, the space of the desired moment will be divided into several parts and each part will get one optimal weighting matrix obtained by genetic algorithm. Multiple weighting matrices could guarantee better performance in each part than one weighting matrix. Direct allocation is used to be contrast to demonstrate the effectiveness of the algorithm. Simulation results show that the new proposed algorithm could achieve much better performance than the traditional weighted pseudo-inverse method. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
