Abstract

In electromagnetic suspension (EMS) systems, faults in the sensors and actuators might result in instability in the system, and could even lead to catastrophic system failures. Thus, it is essential to improve the system reliability and safety. However, since EMS systems are highly nonlinear and open-loop unstable, such systems require further investigation for fault tolerant performance. Therefore, in order to preserve the stability of EMS system after occurring sensor and actuator fault, a fault tolerant controller using virtual sensor/actuator approach is investigated in this work. Control scheme has been verified by simulating a single-axis two-magnet suspension system subjected to failures of the sensor and actuator.
