简介：当数字地为一艘轮船建模时，参数评价的精确性是批评的。有限制的一个参数评价方法被开发，基于变化方法。在变化方法的性能函数和限制方程被分析系统的输入和输出方程构造。参数评价的问题被转变成最少的广场评价的一个问题。参数评价方程被分析以便基于Lagrange增加操作员得到参数的一个优化评价。模拟结果证明这个方法比传统的最少的广场评价好，当识别参数时，生产更高的精确。它在象系统鉴定和参数评价那样的申请的区域有很重要的实际价值。关键词最少的广场评价-参数评价-变化方法-限制基础条款：不到资助号码2009由海军设备部门基础支持了(189)。我皮脂腺囊瘤史在1982出生了。他是在海军海底的学院的一个讲师，中国。他的当前的研究兴趣是海底的航行。
