Abstract
This paper proposes a sticking fault detecting method for controlled auto-regressive
integrated moving average model (CARIMA) which detect the sticking fault
of control input and feedback signal. It consists of model estimation using
recursive least square method with the forgetting factor and fault detection.
In the fault detection, an evaluation function is introduced, and it generates
a fault signal from the input and output data. Numerical simulations are
performed, and it is shown that this method can detect the sticking fault.
