摘要: 本文提出的正交寻优法是适用于复杂非线性目标函数的近似寻优法.它基于逐点线性化 后按梯度法进行寻优,在线性化及求梯度过程中借用正交试验的概念和正交表的性质,简化了 矩阵求逆过程.该法具有计算量小、搜索速度快及对初值不敏感等特点.利用该法设计的某 型惯导平台稳定回路,得到了理想结果.Abstract: The method presented in this paper is an approximate optimization method for nonlinear objective function. Based on point to point linearization, it is optimized by the gradient method. Inverse matrix calculation is simplified by the concept of orthogonal test and orthogonal table in this process. This method possesses the advantages of calculation in small amounts, rapid search and insensitive to initial value. With this method, satisfactory result has been obtained in the design of the stationary system for an inertial guidance platform.
