This manuscript presents a reduced chattering sliding mode control (SMC) strategy for automatically regulating the depth of hypnosis (DoH) during general anesthesia (GA). The controller uses DoH as the controlled variable and assumes an infusion pump as the actuator. A linear model serves as an approximation in the SMC law, while a sigmoidal function is used instead of the sign function to mitigate chattering. The scheme adopts a tracking-based approach to handle induction and maintenance phases of GA. The method is evaluated through simulations with and without pain stimuli and noise, using real-patient pharmacokinetic and pharmacodynamic parameters and incorporating the dynamic behavior of the DoH monitor. Results showed no high-frequency chattering and demonstrated robust performance, suggesting that the proposed approach is promising for real-world clinical applications.
本文提出了一种减少抖振滑模控制(SMC)策略,用于在全身麻醉(GA)期间自动调节催眠深度(DoH)。控制器使用DoH作为被控变量,并假设一个输液泵作为执行器。在SMC律中,用线性模型作为近似,用s型函数代替符号函数来减轻抖振。该方案采用基于跟踪的方法处理遗传算法的诱导和维护阶段。该方法通过模拟疼痛刺激和噪音,使用真实患者的药代动力学和药效学参数,并结合DoH监测仪的动态行为来评估。结果显示,该方法无高频抖振,性能稳定,表明该方法有望用于实际临床应用。

This paper investigates the finite- and fixed-time privacy-preserving formation control problem for multiple quadrotors with input delay and connectivity maintenance. A lightweight confidential interaction protocol based on group key agreement is first proposed to ensure secure communication among quadrotors under limited computational resources. To address the input delay, an extended Artstein’s transformation is introduced to convert the system into a delay-free form, and by integrating potential functions with finite-/fixed-time control techniques, novel formation control algorithms are developed to resolve the delay issue while preserving the initial interaction topology. Leveraging Lyapunov stability theory and bi-limit homogeneous system theory, rigorous theoretical analysis is conducted to derive sufficient conditions for finite- and fixed-time formability of the quadrotor formation system. The proposed framework systematically resolves the coupling challenges among privacy protection, time-delay compensation, and topology preservation. Numerical simulations and flight experiments are carried out to illustrate the effectiveness of the theoretical results.
研究了具有输入延迟和连通性保持的多四旋翼机有限和固定时间保密编队控制问题。为了在有限的计算资源下保证四旋翼机之间的安全通信,提出了一种基于组密钥协议的轻量级保密交互协议。为了解决输入延迟问题,引入了扩展Artstein变换将系统转换为无延迟形式,并通过将势函数与有限/固定时间控制技术相结合,开发了新的群体控制算法来解决延迟问题,同时保留了初始交互拓扑结构。利用李雅普诺夫稳定性理论和双极限齐次系统理论,进行了严格的理论分析,得到了四旋翼编队系统有限和定时成形性的充分条件。该框架系统地解决了隐私保护、时延补偿和拓扑保持之间的耦合问题。通过数值模拟和飞行实验验证了理论结果的有效性。
