摘要
根据现代控制工程中的最小二乘递推算法原理,本文提出了复模态参数识别的非线性最优化递推算法.通过数字算例表明该算法具有节省内存、迭代时间短,能直接识别复模态参数等优点.
In this paper,based on the principle of least square method in modern con- trol engineering,the recursive algorithm of nonlinear optimization in com- plex modal parameter identification technique is presented.The results of examples show that this method gives advantages over others in less quanti- ties of memory,shorter intervals of iteration and direct identification of the complex modal parameters.
