Time-Optimal Control Based on Evolutionary Programming
-
摘要: 在分析时间最优控制问题已有求解方法优缺点的基础上,提出基于进化规划法求解约束时间最优控制 问题的直接方法,研究进化规划求解时间最优控制问题的模型,将约束作为惩罚项包括在目标函数中,以此构造 适应度函数。对线性阻尼振子问题进行了数值仿真,结果表明效果良好。Abstract: An evolutionary programming (EP) based method for solving constrained time-optimal control problems is proposed on the basis of an analysis of the advantages and disadvantages of the existing algorithms, and a mathematical model is developed. In this model, the fitness function is constructed by including the constraints in the objective function as penalty terms. A numerical simulation for the problem of linear damped oscillator shows the effectiveness of the method.
