The focus of the paper is set on modelling of active vibration isolation systems utilising electropneumatic units. Unlike the models empolyed to date, the presented model involves all the relationships describing the pneumatic supply system performance and takes into account all possible leaks in the pneumatic amplifier in the servovalve. The main focus is on modelling friction forces in the structural nodes of the actuator unit. The dynamic model of friction was selected. Results of numerical experiments run in MATLAB-Simulink enviroment were most promising and the selected model proved adequate.
