A delayed-feedback control scheme for suppressing spatial bifurcation and chaotic behavior in open-flow models is presented. It is shown that spatial bifurcation and chaotic behavior never occur when the delayed-feedback controller is designed such that the following two conditions are satisfied: all the poles of the transfer function of each site are inside a unit circle and the H norm of the transfer function is less than one. A simple systematic procedure for design of the delayed-feedback controller is provided. It is confirmed that the theoretical results agree well with the numerical simulations.
