摘要:  针对非线性系统的多参数定标问题,结合最小二乘法和遗传算法各自的优点,提出了一种收敛速度较快、精度较高的混合智能算法。首先通过改进的最小二乘法计算得到问题的次优解,以此作为遗传算法的基因中心值,并将基因范围动态缩小进行进化计算,从而获得最优解。实验结果证明混合算法在工程应用中是有效的。

Abstract: Combined with fast convergence and high accuracy, a hybrid intelligent algorithm was proprosed to solve the parameter calibration of the nonlinear system. The results that computed by the improved least-square algorithm became the the original values of the genetic algorithm where gene range could be dynamically changed. The experiment shows that the hybrid algorithm is valid in practical application.

Key words: calibration, least-square algorithm, genetic algorithm
