The contribution summarieses research on an active vibration control system for heavy loads. The system is modeled as a single DOF oscillatory system with residual damping and a parallel force generator. As the force generator a stsndard air spring is used, whose internal pressure is proportionally controlled either by a flow control valve or a pressure control valve. Either proportional electro-pneumatic transducer is governed by a control voltage generated by an analogue controller based on a hybrid combination of feed-back and feed-forward control circuits. Experimental results on actuator sub-system identification and whole system frequency response funcitions of both modifications are presented. By proper setting of the gains favorite course of FRF coud be optained with no resonanse amplification, as assumed by simulation research.
