Initially, FMEA based on risk priority numbers provided information about the effects in the system, but during the last years different approaches have been developed to obtain a more robust risk evaluation. The proposed enhanced FMEA can provide the quantitative effects of sensor faults in a railway traction drive, in variables such as torque, current and voltages. In addition to the previous work, quantitative effects on overall performance indicators, such as energy efficiency and comfort, are obtained too. Hardware-in-the-loop (HIL)-based fault injection approach has been used to generate fault scenarios. The test platform is composed of a real-time simulator and a commercial traction control unit for a railway application. 2051-3305 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=152538 https://hdl.handle.net/20.500.11984/1675 Failure analysis Railways Traction motor drives Risk analysis Closed loop systems Fault diagnosis Traction Hardware-in-the-loop performance analysis of a railway traction system under sensor faults
