Time delay is usually unavoidable in feedback control systems due to the time spent for measuring and estimating of the system state, calculating and executing of the control forces, etc.This time delay, often leads to instability or poor performance of controlled systems.Thus.the issue of handling time delay has drawn much attention of the control community.Systems with time delay under deterministic excitation have been studied by many researchers.Hopf bifurcation often occurs in time-delayed deterministic systems and has been studied by using the linear stability, analysis method, the invariant manifold reduction, the normal form method, the averaging method and the multiple scales method.Much work has been done on the effect of noise on the bifurcation[1,2].The effect of time-delay on stochastic Hopf bifurcation of quasi-integrable Hamiltonian systems under Gaussian white noise excitations has been studied by the present authors[3].
