  • Estimated resonant frequency in real-time using a systemic circulation model and online system identification.
  • Utilized aortic pressure and blood flow data for frequency estimation.
  • Evaluated control effectiveness using an in vitro mock-up circulation loop.

    • Main Results:

    • The resonant frequency control method effectively provided blood flow.
    • System gain increased under resonant frequency control compared to non-resonant frequencies.
    • The control method demonstrated adaptability to changing physiological conditions.
    • Significant improvement in system performance was observed when physiological conditions varied.

    Conclusions:

    • The resonant frequency control method is an applicable therapeutic strategy for artificial hearts.
    • This control method can adapt to physiological behavior for improved medical care.
    • The findings support the use of resonant frequency control for enhanced artificial heart function.
