【Abstract】 This paper presented the idea and method for controlling the complex dynamic behavior of a rotorbearing system, i.e. bifurcation and chaos, and designed a controller by washout-filter feedback method. Modulating the parameters of this controller can control the stability of the rotor system. Numerical simulation result showed that the dynamic behavior changed rapidly when the rotate speed of the rotor-bearing system increased continually, and that the washout-filter feed back method had a good effect on controlling bifurcation and chaos in above condition.更多还原
