Abstract

In U.K. 60 000 people have a brain tumor and typically are unaware of its presence until symptoms occur. Currently, there is no mass screening available due to limitations in diagnostic techniques. Measurement of intracranial pressure (ICP) [via tympanic membrane displacement (TMD)] is a potential low-cost, accessible solution; however, pressure fluctuations degrade its accuracy. This article solves the problem by assisting participants to precisely track airway pressure profiles. This stabilizes intrathoracic pressure, significantly reducing the fluctuations and enabling accurate diagnosis of ICP. This article develops and evaluates the first model of lung pressure tracking to embed volitional control action. A clinically feasible identification approach is then derived, together with a novel model predictive control (MPC) framework, embedding a valve control subsystem. Results with ten participants confirm that tracking is improved by an average of 22%.
模型预测阀控制,以协助肺压力轮廓跟踪
在英国,6万人患有脑瘤,通常直到症状出现才意识到它的存在。目前,由于诊断技术的限制,没有大规模筛查。测量颅内压(ICP)[通过鼓膜位移(TMD)]是一种潜在的低成本,可获得的解决方案;然而,压力波动会降低其精度。本文通过帮助参与者精确跟踪气道压力分布来解决问题。这稳定了胸内压,显著减少波动,使ICP的准确诊断成为可能。本文开发并评价了首个嵌入意志控制作用的肺压跟踪模型。然后推导了一种临床可行的识别方法,以及一种新的模型预测控制(MPC)框架,该框架嵌入了一个阀门控制子系统。10名参与者的结果证实,跟踪平均提高了22%。

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.
