An innovative digital method for the dynamic simulation of DC electromechanical systems

In this paper, an innovative digital simulation method, named 'R-K-T' metho d, is presented. The new methodology combines Runge-Kutta and trapezoidal m ethods and possesses the advantages of both of them. The errors featuring t he proposed method are analysed and their correction is worked out. As a ca se study, the circuit model of a small DC motor, acting as the engine start er of a road vehicle, is considered; the proposed methodology is applied to carry out the dynamic simulation of the electromechanical device. The resu lts are obtained efficiently and with a good degree of accuracy; in particu lar, the numerical oscillations are suppressed. (C) 1998 Elsevier Science L td. All rights reserved.
