Abstract: This paper proposes a scheme of fault detection for
piezoceramic actuator described by so-called sandwich system models with
hysteresis. In this scheme, the state variables of the system are estimated
by a non-smooth observer due to the effect of hysteresis inherent in the
piezoceramic actuator can not be neglected. The fault detection is based on
the residual between the output of the observer and the actual data. In the
simulation, the detection of the faults happened in actuator, i.e. input
linear subsystem, output linear subsystem, and the output sensor are
presented, respectively.
