| 摘 要： | 大多数现有的鲁棒故障诊断系统集成设计方法都采用基于 2范数的残差评价函数。本文首先讨论了以 2范数作为残差评价函数的问题 ,然后提出了一种新的残差评价函数 ,并以此为基础 ,进一步提出了相应的故障诊断系统集成设计方法。它可以有效地解决现有的基于 2范数方法的问题 ,使所得到的故障诊断系统更容易设计和实现

| Abstract: | In most of the existing integrated FD system design approaches, the 2 norm of residual signal is widely adopted as the residual evaluation function. In this paper, a problem of the 2 norm based evaluation function is firstly discussed. Then a new kind of evaluation function based on the absolute value of residual signal and the corresponding integrated design approach to FD systems are proposed. It can solve the problems in 2 norm based method, so that the resulted FD system is simple and easy to be implemented and designed. |
