Semi-active control of magnetic fluid damper is a new generation of intelligent vibration suppression driver recently developed in the world. This paper mainly introduces the MTS experimental system and its related research results. The experimental system consists of hydraulic feedback exciter, data acquisition and processing computer unit, sensor and other hardware and software. The experimental system can display the time response signal such as the relative displacement, velocity and damping force generated by the damper in real time, The basic characteristics of the damping force to the relative velocity curve. The experimental results show that the intelligent driving device exhibits typical hysteresis nonlinearity and systematically describes the new generation of semi-linearity by analyzing the experimental data stimulated by a large range of control currents and a wide range of frequency and amplitude single-harmonic signals Active control of intelligent drive components of the main performance characteristics.
