A set membership identification approach is provided to deal with the problem of fault detection of systems with models not precisely known. 为了处理数学模型不精确已知系统的故障检测问题，给出了一种故障检测的集员辨识方法。
Since the result of the estimation was a set of the weights of the RBF network, it could be easily used to predict the interval of the practical system output. 由于集员辨识算法所得到的是网络输出权值的集合估计，在系统运行过程中，可以很方便地利用所建模型预测实际系统的输出范围。
