This paper proposes a hardware redundancy based actuator fault detection concept for the control
of a heavy metro vehicle car body. Because of the specific properties of collocated actuator/
sensor pairs it can be shown that the proposed method is simple, reliable and inexpensive.
Additionally, it avoids the necessity to accurately model the flexible structure under investigation
which would be necessary in analytical redundancy based methods. Furthermore, the
concept is validated utilizing a 1/10 scaled laboratory model of a heavy metro vehicle car body.
