This paper proposes a robust suppression sliding mode controller design for uncertain Duffing-Holmes chaotic systems. A form of time-varying second-order differential equation is organized to describe the dynamical system. Control system performance is proved robust against parametric uncertainties and external disturbances. The control input involves a discontinuous switching control input which is used to deal with the uncertainties and disturbances. Illustrative example is given. Input chattering is remarkably eliminated and trajectory tracking is effectively achieved.
