Comparison of two simplified mathematic models of pneumatic system

Abstract

This paper deals with comparison of two methods of pneumatic systems modelling. The first one is mathematical modeling by means of RHD resistances, which are resistance to motion R, resistance to acceleration H and deformation resistance D. The second approach can be called as classical. This method is based on state equation of gas, continuity equation and motion equation. Output characteristics of models are compared with data obtained by measurement in the end.
