Abstract :
Bond graph is an integrated method of modeling which would be suitable for modeling mechatronic systems that are usually formed from electrical, mechanical and hydraulic systems. This paper presents a new bond graph model for one the important components of mechatronic systems: op amp. This model allows considering finite gain and non-zero input impedance op amps. To develop this method, open loop gain equation, information signals, and bicausality concept are applied. To represent the validity of the method, some examples are investigated and the state space equations are obtained.
