It is about the modeling and the simulation of the D.C machines under the Matlab software into which the libraries Simulink and SimPowerSystems are integrated. These libraries contain blocks of modeling which allow indicates it, simulation, the implementation and the system monitoring of communication and processing of the signal. The objective thus is to study the operation of the various types of D.C machines.
