Abstract
An energetic description of the electric transport urban system ASTRAIK
415T is proposed according to a specific formalism. This is used to simulate the
trolleybus system, equipped with a chopper and a direct current series motor. DC series
motor is still used for trolleybus and metro, driven by a GTO or IGBT chopper
μC-controlled, which allows the implementation of command algorithms. From this
synthetically representation a complete model of the electromechanical system was
implemented using the Matlab-Simulink simulation environment. A control structure
was deduced through model inversion. This will allow the study of the transient
phenomena and the implementation of different command laws taking into account the
minimum energy losses.
