| 摘 要： | 针对传统的线性回归分析法在幂函数参数辨识寻优时容易陷入局部极小值,不能有效克服负荷建模中存在的非线性和不连续性等不足,分析了进化规划在幂函数参数辨识中的应用,通过仿真算例对上述两种方法的辨识精度进行比较分析,结果表明进化规划能够实现全局搜索,适合解决多极值的非线性优化问题.

| Abstract: | The conventional linear regression analysis method may easily lapse into local minimum points in the condition of optimizing power function parameter identification and it can not recover such defects as nonlinearity and discontinuity in modeling.The article analyzes application of evolutionary programming in power function identification and comparatively analyzes identification accuracy of the above two methods by simulation examples.The result makes it clear that global search can be accomplished by evol... |
