摘要
目前常用的概率积分法求参方法对参数初值有较强的依赖性,不合适的初值将导致求参过程发散。相对于正交设计,均匀设计主要考虑将设计点均匀地分散在试验范围内,而不再考虑“整齐可比”性,这样可以在较少的试验次数内较快逼近参数真值,减小了初值选取对使用者的经验要求,扩大了求参方法的适用范围。
The probability- integral method commonly used at present for parameter determination has strong dependence on the initial values. Inappropriate initial values may lead to the diverging of the parameter determination process. The uniform design method is to uniformly distribute the design points in the test range without considering "the regularity comparability" so as to make it possible to rapidly approach the exact values of parameters in fewer tests and reduce the dependence on the users" experience in initial value selection, thus expanding the application range of the parameter determination.
