Abstract	This research was developed and aimed at an embedded controller to achieve an active variable damping control to magnetorheological fluid damper under impact load. Its character of impact load is firstly analyzed and its working principle of MR damper applied into anti-shock engineering design is also introduced. Then, an impact test has been done by using the developed test rig in order to investigate response time of MR dampers under impact load. Based on the measuring results, some factors effecting time delay of MR damper under impact load are analyzed. And simulation results prove that current response time can be gradually reduced with its resistance increase and can be gradually increased with its equivalent inductance increase, yet its frequency of PWM wave and temperature has little influence on it. Considering its strong nonlinear and uncertainty of a MR damper under impact load, and a large of signal processing and controlling operation, in order to improve its real-time, reliability and stability of control system, an embedded measuring-controlling system based on ARM and DSP processor is designed and developed for its engineering application of semi-active vibration control system. The embedded system design scheme, its each part design and the system software design are all introduced. Finally, experimental results show that the developed embedded system can effectively reduce time delay of MR damper and achieve a good semi-active vibration control effect.
