Schematic of gas turbine with time delay feedback actuator
Grahic Jump Location
Simulation of gas turbine with a faulty actuator. At t=25 s, the time constant of the actuator was changed to Ts=0.01 from 0.356 s. The top plot (a) is the rotational speed. The middle plot (b) is the filter, and the bottom plot (c) is the residual. Note the change in the residual.
Grahic Jump Location
Coefficients of the fourth order linear auto-regressive process (a1,a2,a3,a4). The fault occurs at 2500th sample. Note the change in the coefficients.
