Control Systems in Engineering

Two differential flatness‐based bidirectional tracking robust controls for a DC/DC Buck converter‐DC motor system are designed. To achieve such a bidirectional tracking, an inverter is used in the system. First control considers the complete dynamics of the system, that is, it considers the DC/DC Buck converter‐inverter‐DC motor connection as a whole. Whereas the second separates the dynamics of the Buck converter from the one of the inverter‐DC motor, so that a hierarchical controller is generated. The experimental implementation of both controls is performed via MATLAB‐Simulink and a DS1104 board in a built prototype of the DC/DC Buck converter‐inverter‐DC motor connection. Controls show a good performance even when system parameters are subjected to abrupt uncertainties. Thus, robustness of such controls is verified.
