摘要: 针对开关系统,给出了数学模型并引出了其最优控制问题,提出开关系统最优控制问题的加权粒子群算法,给出了相关的推理过程及算法步骤。加权粒子群算法不必找出支付泛函关于时间的显式表达,就可以找到其最优解,同样适用于其子系统为非线性的情形。分析了粒子群算法快速全局优化的特点,说明该算法能找到优化问题的全局最优解。以开关动态系统和一般开关线性二次问题的数值算例验证了该方法的有效性。

Abstract: Concerning switched systems,the switched systems and an optimal control problem are formulated,the weighted particle swarm algorithm for the optimal control problem of switched systems is proposed,and the steps of the algorithm are given.The global optimal solution of the optimal problem could be obtained fastly by this algorithm and the global constringency of this algorithm is analyzed.Numerical examples for both switched dynamical systems and general switched linear quadratic(GSLQ) problems are given to demonstrate the feasibility and effectiveness of the proposed approach.
