Abstract

In this paper, a complete quarter MR suspension system based on modified Bouc-wen model is presented to investigate the nonlinear dynamical behaviors. The bifurcation varying single-frequency excitation is conducted, and the corresponding phase plane and Poincare in specific frequency for periodic, quasi-periodic and chaotic motions are given respectively. Then a linear feedback controller is designed, and the stability of the controlled system is carried out. Finally, the numerical simulations of the MR suspension system are demonstrated the effect of the control method.
