Execution time Validation of the mathematical models of a electric motor in Soft Real Time simulation

This paper presents the simulation and comparison of models of first and second order of an electrical machine, in Soft Real Time. First, it describes the real-time systems and their classification. After is considered the electromechanical circuit of a Series wound DC motor, for obtaining the first and second order equations which represent the system (In continuous time and discrete time). The models obtained are simulated in SIMULINK and their parameters (electric current and angular speed) are compared between them for obtaining the relative error. Once compared the responses of the models, the execution time of the finite difference models is obtained and compared with data acquisition device execution time.
