In this paper, the regular and chaotic oscillations in a modified Rayleigh-Liénard system under parametric excitation are studied. Two subharmonic resonant states are generated using the multiple time scales method and the effects of the system parameters on the frequency-response curves are investigated. Bifurcation structures and transitions to chaos for the first subharmonic resonant state are numerically investigated via the fourth-order Runge-Kutta integration algorithm, and

The influences of the nonlinear damping coefficients, cubic nonlinearity coefficient and small dimensionless coefficient on the bifurcation sequences are also investigated. As results, it is found that the nonlinear damping coefficients and cubic nonlinearity coefficient can be used to control the presence of chaos in the system while decreasing of the small dimensionless parameter removes chaos from the system.
