Electronic Control System for the Left Ventricular Assistance Device

The number of heart transplants is constantly increasing. Each year, it grows by around 60% due to the health problems plaguing the world's population. Furthermore, the lack of available transplanted organs and the waiting list greatly increases and can last for years. All these reasons make it increasingly difficult to get a heart transplant. Solutions such as artificial organs are gaining more and more prominence and are in great demand. Considering the advancement of science and technology, new research shows great hope in prolonging and improving the quality of life for many patients. Among these researches is the Left Ventricular Assist Device (LVAD), which uses auxiliary pumps along with the natural heart of the person, allowing a longer waiting time in the transplant queue and giving a quality of life. This work aims to implement autonomous electronic control over this device, allowing autonomous speed control over the pump motor. This method gives patients better control and greater freedom to practice their daily lives. Another important reason is the economic factor, which aims to reduce costs and allow greater popular reach. In this work, the tests were carried out on only the Brushless Direct Current Motor (BLDC). The results are demonstrated in numerical and graphic form for better illustration.
