Research on a Program Angle Optimization Method for Supersonic Rocket Target

doi:10.3969/j.issn.1000-1093.2015.04.011

Abstract

Abstract: An optimization method of pitch program angle is proposed for the optimization problems of level flight trajectory of supersonic rocket target. Considering the initiation and impact point of rocket target and the level flight state constraints, the pitch program angle optimization model is built on the longitudinal flight plane of rocket target. The Process constraints are transformed to the pitch program angle constraints, and the optimal control problems are translated to the nonlinear programming problems based on Gauss pseudo spectral method. And then the nonlinear programming problems are solved by sequential quadratic programming method. Simulation results show that this proposed method can quickly obtain the optimal program pitch angle, and has good robustness.

Key words: ordnance science and technology, supersonic rocket target, level flight trajectory, program angle optimization, Gauss pseudo spectral method
