(2019) Computational guidance using sparse Gauss-Hermite quadrature differential dynamic programming. IFAC-PapersOnLine, Volume 52, Issue 12, 2019, pp. 13-182405-8963https://doi.org/10.1016/j.ifacol.2019.11.062https://dspace.lib.cranfield.ac.uk/handle/1826/15091This paper proposes a new computational guidance algorithm using differential dynamic programming and sparse Gauss-Hermite quadrature rule. By the application of sparse Gauss-Hermite quadrature rule, numerical differentiation in the calculation of Hessian matrices and gradients in differential dynamic programming is avoided. Based on the new differential dynamic programming approach developed, a three-dimensional computational algorithm is proposed to control the impact angle and impact time for an air-to-surface interceptor. Extensive numerical simulations are performed to show the effectiveness of the proposed approach.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Computational guidanceDifferential dynamic programmingSparse Gauss-Hermite quadratureImpact angleImpact timeArticle
