Abstract

This paper presents an optimized controller to achieve better synchrony in human-ventilator interactions. An experimental platform was built by using data acquisition, a set of signal collectors, and a blower wired with driver circuit. The related signals were all acquired and processed by a program written with the optimized controller in LabVIEW. Then, the comparative experiments were conducted in this paper. Specifically, in the experiments, the conventional PID controller led to the obvious pressure spike which was 2cmH2O higher than inspiratory pressure, whereas the proposed controller can decrease the pressure quickly without the pressure spike when switching to the expiration state. Also, the Pressure-Volume Loop indicated that the area from the optimized controller was smaller than the conventional PID controller. These results showed a good performance from the proposed controller in terms of synchrony, and this optimized controller will be useful for the future ventilation.
