The paper presents concept of an active suspension of an autoparametric pendulum system. The suspension consist of a magnetorheological (MR) damper and a shape memory alloy spring (SMA). The influence of non-linear damping and SMA stiffness on regular and chaotic vibrations and their stability, near the main parametric resonance has been analyzed. This active suspension allows control of position of periodic or chaotic regions. Additionally, the proposed suspension does not reduce the absorption effect.
