摘要
Abstract
Design of control rate during low-lhrust trajectory optimization process is a typical optimal control problem in nonlinear dynamics. Aiming at specific problems, direct or indirect optimal algorithms are applied widely. For simplifying the optimal problem model, shape programming theory is adopted to simulate the low-thrust action trajectory. So that dynamics optimal control problems is transformed to polynomial parameter optimization. Combined with asteroid group exploration, a hybrid optimization algorithm PSO-DE (particle swarm optimization & differential evolution) is utilized to resolve parameters. And finally a pattern searching local optimization algorithm is used for quadratic optimization to satisfy the precision demand.关键词
