Abstract

This paper presents the modeling and experimental validation of a new topology for the DC/DC Buck power converterDC motor system. The main objective of this topology is to achieve a bidirectional rotation on the DC motor shaft by using a DC/DC power converter. As a result of applying Kirchhoffs current and voltage laws the system mathematical model is obtained. Also, an analysis in steady-state of the system is presented. While, the reference trajectory generation associated to the states and controls of the system (expressed in terms of the voltage converter and motor angular velocity) is performed via differential flatness, which allows a trajectory tracking control in open-loop. The experimental validation of the herein presented model is carried out by means of Matlab-Simulink, ControlDesk, and a DS1104 from dSPACE. The experimental results confirm the validity of the mathematical model, for the general case, i.e., the time-varying trajectory tracking and not only the constant trajectories case.
