Popis: Electrical magnetic suspension system is widely used in medium-low and high speed maglev vehicles. The system is an unstable and nonlinear complex system. Accelerometers are widely used in the system to obtain acceleration information for electromagnets, and these sensors are critical to suspension control system. Since these sensors are mounted on an electromagnet and subjected to large vibrations, they are prone to malfunction. In this paper, the acceleration sensor is diagnosed by gap signal. Once the acceleration sensor fails, the acceleration sensor signal can be isolated and the system can operate normally. Experimental results have validated the effectiveness of the proposed method.
