Abstract

In order to solve the trajectory tracking task associated with the bidirectional DC/DC Buck power converter-inverter-DC motor system, a sensorless passivity-based control is presented for the first time. In particular, the exact tracking error dynamics passive output feedback (ETEDPOF) methodology is used. To this end, the required nominal trajectories for the synthesis of the ETEDPOF-based control are defined by means of the system differential flatness property. With the intention of verifying the designed control performance, experimental tests are accomplished through Matlab-Simulink, ControlDesk, and a DS1104 board. The obtained experimental results show a good performance of the ETEDPOF-based control.
