Abstract:

This paper presents an anomaly detection method for middle-low suspension system based on an improved canonical correlation analysis （CCA） by using the multiple types of monitoring data from the suspension system. A better threshold and a higher detection rate can be obtined by the proposed method in comparison with the thresholds by K-medoids -based method and the support vector data description （SVDD）-based method.

Key words:suspension system;anomaly detection;canonical correlation analysis
