[Abstract]:According to the Lagrange equation of the second kind, the dynamic equation of the two-body vibration machine system is established, and the washoutfilter controller is designed to control it. The inverse control of the Hopf bifurcation of the system is realized by using the Hopf bifurcation explicit critical criterion. In this paper, the linear control gain bifurcation diagram of the system is given. Based on the central manifold canonical form theory, the range of nonlinear control gain for stabilizing the bifurcation limit cycle is determined. The nonlinearity is obtained by the limit cycle amplitude expression of the Hopf bifurcation. The amplitude-controlled effect of the control gain, The control effect of nonlinear control gain on amplitude is described. The numerical results show that the nonlinear control gain is positively correlated to the amplitude of the system, which shows that the washout-filter controller is effective and feasible to control the amplitude of the dual mass vibration machine system.
