Due to the engineering progress in the past few years, it is possible to study the behavior of actuators carefully and define them at a very early design stage with the help of modeling and simulation approaches. Following this information, it is critical to have a model capable of simulating and testing the behavior of an electromechanical actuator, since a lack of that information may impede to further development of a functional prototype project. The necessity and importance of the work described in this paper come to ensuing this scene. The present project focuses on the problem of the design and development of an electromechanical actuator and its scope is to create a model capable of simulating the actuator and to develop HiL test environment to have a reliable model at the end.
