Abstract :
[en] The paper presents a closed loop approach for the lung function tests of forced oscillation technique. In this method it is important to ensure that the desired excitation signal to be applied at the patient’s mouth will be delivered by the lung function testing device, without introducing distortions and nonlinear effects. A novel PID auto-tuner is applied in an initial phase of the investigation, without the patient, to verify whether the closed loop control can be implemented. The results are promising, showing that the auto-tuner is able to perform well and ensure the desired signal at the output of the device, within safety limits for the control effort (air flow).
