Dynamic Behavior of Electromechanical Linear Actuators by Using Unified Approach of Bond Graph

The study of the dynamics of a real system requires the modeling of the system. Models of the systems are simplified, abstracted constructs used to predict their behavior. Using the language of bond graph, one may construct models of all type of physical systems. The models will be mathematical models represented by uniform graphical notation and a small set of ideal elements. In this paper the dynamic behavior of electromechanical linear actuators is being discussed with the motive is to develop a universal model by using unified approach of bond graph that gives the opportunity to simulate both existing and new systems without having to remodel the entire system each time. The work refers to analyze the functional parameters of electromechanical linear actuators by modeling of different components of EMLA using bond graph. Given a bond graph model, causality can be assigned and algebraic-differential equations can then be obtained in an algorithmic way.
