| Abstract | In conventional Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) controller design, the designer should experiment with four different weighting matrices by trial-and-error method in order to get the flying quality requirement and the robustness. This method is a time consuming, inefficient and non-optimal method. To solve this problem, a LQG/LTR flight controller optimal design method based on differential evolution algorithm is proposed in this paper. In the optimal design, a Kalman filter is optimal designed by optimizing two weighting matrices based on a reference model and differential evolution algorithm firstly. So the optimal target feedback loop which satisfies the performance requirement is obtained. Secondly, the principle of the aircraft equivalent system analog match is used for reference to design an optimal state feedback gain matrix by optimizing another two weighting matrices. To validate the effect of this optimal design method, a longitudinal LQG/LTR flight controller is optimal designed based on differential evolution algorithm. The simulation results show the high effectiveness of this optimal design 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.
