针对化工过程数据强非线性和动态性的特点,提出了一种基于动态等距离映射(Dynamic Isometric Mapping,DISOMAP)流形学习的非线性过程故障检测方法.该方法首先采用DISOMAP算法提取训练样本的子流形特征,自适应学习近邻点参数,保留了采样数据的流形结构,然后运用线性回归方法得到原空间和降维子流形空间的投影映射,从而将观测数据从原高维空间映射到低维嵌入空间,最后在变换后的低维空间构造统计量T2.SPE进行监控.TE过程的仿真结果表明,所提出的DISOMAP故障检测方法可以比核主元分析(Kernel Principle Component Analysis,KPCA)更为有效地监控过程变化,检测到故障的发生.
