| 摘 要： | 介绍了如何应用参数最优化方法将具有状态变量不等式约束和控制变量不等式约束以及终端等式约束的最优控制问题转化为静态非线性规划问题,并提出了将求解静态约束最优化问题的系贯加权因子法,即ＳＷＩＦＴ(ＳｅｑｕｅｎｔｉａｌＷｅｉｇｈｔ－ＩｎｃｒｅａｓｉｎｇＦａｃｔｏｒＴｅｃｈｎｉｑｕｅ)法推广为求解动态约束最优化问题的增广ＳＷＩＦＴ法。最后用计算美国航天飞机的返回最优轨迹说明了该法的可行性。

| Abstract: | An introduction is given to the transfonnation of optimal control problem with state inequality constraints,control inequality constraints and tenninal constraints into static nonlinear programming problem with parameterized optimization method, and a new augmented-SWIFT is also presented.The SWIFT(Sequential Weight-Increasing Factor Tech-nique)is used in static constrained optimization problem whereas the new auginented-SWIFT is extended to calculate dynamic constrained optimal control problem,Finally,the feasibility of this algorithm is certified by an example of a reentry optimal trajectory. |
