Sensorless Tracking Control for a “Full-Bridge Buck Inverter–DC Motor” System: Passivity and Flatness-Based Design

“…Some applications that have been profited, although some kind limited, from using this system can be found in mechatronic systems [54], robotic arms [55], and wheeled mobile robots [56]- [58]. • By using the "MIMO DC/DC Buck converter-inverter-DC motor" system [31]- [34] the unidirectional rotation restriction associated with the DC motor shaft is overcome, since an inverter circuit is introduced between the Buck converter and the DC motor. An application recently developed that uses such a system can be found in [34], where the problem of renewable energy power source based on fuel cells was presented by Chi et al in 2020.…”

“…Later, Hernández-Márquez et al in [33] employed two robust controls based on flatness for solving the angular velocity tracking task of the DC/DC Buck-inverter-DC motor system. Lastly, a control based on the adaptive sliding mode technique with neural network estimation for the bidirectional DC motor system consisting of a DC/DC Buck converter, a full bridge inverter, and a DC motor was investigated by Chi et al in [34].…”

“…One of those topologies is the DC/DC Buck power electronic converter. This topology has been extensively used as a driver for DC motors; the most relevant contributions regarding the latter has been reported in [2]- [34]. Such contributions can be classified in "SISO DC/DC Buck converter-DC motor" [2]- [30] and "MIMO DC/DC Buck converter-inverter-DC motor" [31]- [34] for unidirectional and bidirectional movement, respectively.…”

The unidirectional movement is related to the clockwise rotation of the motor shaft, while the bidirectional one implies both, the clockwise and the counter-clockwise rotation of the motor shaft.…”
