Abstract

Mechanical ventilators are essential for patients who are unable to breathe independently. The aim of this article is to develop a systematic control design methodology that achieves accurate tracking of both the pressure and flow to ensure comfortable breathing for the patient. A hybrid controller is introduced that ensures improved baseflow tracking performance. The actual controller design leverages frequency-based techniques and is based on static decoupling and the factorized Nyquist criterion. Furthermore, a theoretical stability analysis of the hybrid controller is presented. The presented control strategy is implemented in a real ventilator, and it is demonstrated that the tracking performance is improved by conducting an experimental case study.

改进机械通气压力和流量跟踪的混合控制

对于不能独立呼吸的病人，机械呼吸机是必不可少的。本文的目的是开发一种系统的控制设计方法，以实现准确的压力和流量跟踪，以确保患者舒适的呼吸。引入了一种混合控制器，保证了基流跟踪性能的提高。实际的控制器设计利用了基于频率的技术，并基于静态解耦和因式奈奎斯特准则。此外，对混合控制器的稳定性进行了理论分析。将所提出的控制策略应用于一个实际的呼吸机中，并通过实例研究证明了该控制策略的跟踪性能得到了改善。

期刊介绍： The IEEE Transactions on Control Systems Technology publishes high quality technical papers on technological advances in control engineering. The word technology is from the Greek technologia. The modern meaning is a scientific method to achieve a practical purpose. Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware. A primary purpose of the IEEE Transactions on Control Systems Technology is to have an archival publication which will bridge the gap between theory and practice. Papers are published in the IEEE Transactions on Control System Technology which disclose significant new knowledge, exploratory developments, or practical applications in all aspects of technology needed to implement control systems, from analysis and design through simulation, and hardware.
