摘　　要：本文介绍一种多元插值逼近和动态搜索轨迹相结合的全局优化算法.该算法大大减少了目标函数计算次数,寻优收敛速度快,算法稳定,且可获得全局极小,有效地解决了大规模非线性复杂动态系统的参数优化问题.一个具有8个控制参数的电力系统优化控制问题,采用该算法仅访问目标函数78次,便可求得最优控制器参数。A new global optimization algorithm based on multi-dimensional interpolation function coupled with dynamic search trajectories is presented in this paper. The algorithm can reduce the times of the objective function evaluation greatly and can find the global minimizer of an unknown function of several variables. A good result is obtained when the algorithm is applied to find the optimal feedback gain matrix of a complex power system.
