Traditional field weakening is achieved by means of resistances\u00a0 and contactors wich\u00a0 inserting\u00a0 and\/or shunting in\u00a0 field circuits. It is characterized by shock currents, torque and speed as well as by increased energy consumption. To eliminate these disavantages\u00a0 paper proposes separate control of\u00a0 armature,\u00a0 series and shunt windings\u00a0 of Series\/Compound DC motor and supply their own power converters. Keeping hyperbolic mechanical characteristic of these motors requires setting the series field\u00a0 current equal to or less than armature current. Developed control system is equipped with a single loop for series field and two loops for armature with a\u00a0 current and speed controllers. Imposing series excitation current required is achieved through a special computer based on actual values \u200b\u200bof current and rotor speed. Control system design was made based on a mathematical model and\u00a0\u00a0 use\u00a0 of default instrument of Matlab-Simulink for tuning of PID controllers. Simulation results demonstrate the system&#8217;s ability to control separate windings for continuous speed adjustment in both areas, strictly limiting the rotor current, reducing energy consumption and ensuring the imposed\u00a0 performance indicators. The proposed control method is recommended for use in electric<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2014\/189.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-191\" src=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/wp-content\/uploads\/2015\/03\/images1.jpg\" alt=\"images\" width=\"100\" height=\"104\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Abstract\u00a0 This paper focuses on the problem of the control system of Series\/Compound DC motor in both areas of speed adjustment.
