Shipboard cabinets equipped with sophisticated electronic equipment have very high vibration control requirements, and an active control method is used to realize multi-frequency vibration control of ship-borne cabinet in order to reduce the influence of multi-frequency vibration on ship effectively. Firstly, a set of active vibration control test system for a model cabinet was established based on stack piezoelectric actuators. Then, considering the practical necessity, a multi-frequency vibration control strategy using parallel-form adaptive filters was adopted to carry out the single-input single-output and four-input four-output experiments of three frequencies, and self-adaptive ability of the control system for external excitation and control channel changes were also studied. The experimental results show that the control system can effectively suppress the low frequency line spectrum vibration of the controlled points. At least 85% vibration reduction can be achieved in the single-input single-output case，and about 60% of each controlled point in four-input and four-output system.
