主 题:Multisource stochastic factors Gaussian white noise K-L decomposition Hopf bifurcation Random parameter
摘 要:The article mainly explores the Hopf bifurcation of a kind of nonlinear system with Gaussian white noise excitation and bounded random ***,the nonlinear system with multisource stochastic fac-tors is reduced to an equivalent deterministic nonlinear system by the sequential orthogonal decomposi-tion method and the Karhunen-Loeve(K-L)decomposition ***,the critical conditions about the Hopf bifurcation of the equivalent deterministic system are *** the same time the influence of multisource stochastic factors on the Hopf bifurcation for the proposed system is ***,the theorical results are verified by the numerical simulations.
