It acts in this TP of the regulation the speed of a D.C Motor with separated excitation, supplied with a chopper series, by using a regulator of the Proportional-Integral type (PI). The chopper is a static inverter allowing, starting a source of voltage U continues fixes, to obtain continuous a U_c voltage of variable median value. One uses a static switch for ` to chop ` the voltage continues and to feed a load. We will be interested in the particular case of a chopper series whose one can order the cyclic report/ratio α.
