The aim of this paper is to present some results of a study of an electropneumatic active vibration control system (AVCS) utilizing a pneumatic spring and a proportional electropneumatic transducer. It is treated as a one degree of freedom linear oscillatory system, working predominantly in the vertical direction. A discussion of various AVCS models and respective linear control laws is followed by a short description of the full-scale dummy system aimed for the driver's seats of heavy earth-moving machines and trucks. Some experimental results are presented too.
