Abstract A delayed feedback method for controlling a three‐generator infinite‐bus system is investigated by computer simulation. Nothing but the output signal from the system is used for control. The time series of the phase angle of generators with a transmission line fault shows irregular motion and step‐out. It is found that the irregular motion of the electric power system is coerced onto stable equilibrium points with six stable manifolds by the same control law as the delayed feedback method. © 2006 Wiley Periodicals, Inc.
