An innovative digital method for the dynamic simulation of DC electromechanical systems
In this paper, an innovative digital simulation method, named `R-K-T' method, is presented. The new methodology combines RungeKutta and trapezoidal methods and possesses the advantages of both of them. The errors featuring the proposed method are analysed and their correction is worked out. As a case study, the circuit model of a small DC motor, acting as the engine starter of a road vehicle, is considered; the proposed methodology is applied to carry out the dynamic simulation of the electromechanical device. The results are obtained efficiently and with a good degree of accuracy; in particular, the numerical oscillations are suppressed.
