A Robust Differential Flatness-Based Tracking Control for the 'MIMO DC/DC Boost Converter-Inverter-DC Motor' System: Experimental Results

Abstract

By designing a robust control, for the first time in literature, the tracking task associated with the MIMO DC/DC Boost converter-inverter-DC motor system is solved. Such robustness is achieved through the exploitation of the differential flatness property related to the system and by a suitable design of auxiliary controls. With the aim of verifying the performance of the robust control, a platform of the system along with MATLAB-Simulink and a DS1104 board are used. The experimental results show the good performance of the system in closed-loop even when electrical abrupt changes are considered in some parameters of the Boost converter and when a mechanical load perturbation is applied.
