Abstract

this paper presents the development of a fault-tolerant scheme through an analytical redundancy approach for actively controlled railway wheelsets. The main aim of the study is to maintain the basic control of the rail vehicles in the event of actuator malfunction and to ensure the vehicle stability and good curving performance without the need for additional actuators. The presented fault-tolerant strategy mainly consists of a fault detection and isolation (FDI) scheme and re-scheduling of the controllers. The FDI has been developed through the use of a model-based approach to identify actuator and sensor failures and the re-scheduling of the controller has been investigated with the optimization of control gains tuned to deal with different failure modes. Computer simulation has been used to assess the system performance of the proposed fault tolerant strategy.
