Research on FDIR of Key Sensors for Single Electromagnet Suspension System

The maglev train suspension system relies on some sensors to collect signals for suspension control. Therefore, the working state of sensors is directly related to the safety of the maglev train. In this paper, an effective fault detection, isolation, and data recovery (FDIR) strategy for key sensors of an electromagnet suspension system are proposed. And an offline verification of this FDIR strategy was conducted on a LabViewplatform. Experimental results show that the proposed strategy can satisfy FDIR requirements, and is accurate and effective.
