While analyzing the behaviour of complex systems it is not practical to carry out the simulation of the complete model a the physical level In order to move from simulations at tne physical level towards system modeling with more abstract representations. it is sometimes necessary to use lumped representations of a initially continuous system. Some of these lumped elements will be represented by a black-box model defined by a certain transfer function. This work addresses the problem of the identification of a continuous syster, namely a thermo-pneumatic microacruator. from irs ransient behavior as obtained from finite element modeling The influence of the integration algorithms is studied and a solunon is proposed to avoid its influence in the extracted transfer function. The final representation of the system is used in the simulation of a micropump by using an electronic simulator.
