Mechatronic Design and Robust Control of an Artificial Ventilator in Response to the COVID-19 Pandemic
2020
2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)
Preserved Fulltext
In this sense, this work presents a proposal for the robust mechatronic design and control of a low-cost non-invasive ventilator, for which rapid prototyping manufacture strategies such as 3D printing ...
In order to guarantee the reliability of the system operation, in this work, a robust control scheme based on super-twisting sliding modes is proposed, which guarantees the trajectory tracking control ...
Therefore the regulation of the compression cycle of the AMBU becomes a problem of trajectory tracking control, which is achieved for the purposes of this paper, through sliding modes super-twisting robust ...

Effects of varying engine stroke length and compression ratio were not found to give any large advantages. ...
The development of a full-cycle engine simulation model is described, and extensive simulation results are presented, giving insight into engine operating characteristics and performance. ...
It can also be seen from the piston motion trajectory that the free-piston engine motion is asymmetrical around TDC, and the engine spends more time in the compression than in the expansion phase of the ...
