In this paper, we introduce a variable-gain control strategy for mechanical ventilators in the respiratory systems. Respiratory systems assist the patients who have difficulty breathing on their own. For the comfort of the patient, fast pressure buildup (and release) and a stable flow response are desired. However, linear controllers typically need to balance between these conflicting objectives. In order to balance this tradeoff in a more desirable manner, a variable-gain controller is proposed, which switches the controller gain based on the magnitude of the patient flow. The effectiveness of the control strategy is demonstrated in experiments on different test lungs.
在本文中，我们介绍了一种用于呼吸系统中机械通气机的可变增益控制策略。呼吸系统辅助那些自主呼吸有困难的患者。为了患者舒适，期望有快速的压力建立（和释放）以及稳定的流量响应。然而，线性控制器通常需要在这些相互冲突的目标之间进行平衡。为了以更理想的方式平衡这种权衡，提出了一种可变增益控制器，它根据患者流量的大小切换控制器增益。在不同测试肺上的实验证明了该控制策略的有效性。
