CPS: Small: Control Subject to Human Behavioral DisturbancesThe objective of this research is to develop an integrated methodology for control system design in situations where disturbances primarily result from routine human behavior, as, for example, in future artificial pancreas systems where meals and exercise are the main disturbances affecting blood glucose concentration. The approach is to recognize that human behavioral disturbances (i) are generally random but cannot be treated as zero-mean white noise processes and (ii) occur with statistical regularity but cannot be treated as periodic due to natural variation in human behavior. This emerging class of problems requires (i) the derivation of new mathematical representations of disturbances for specific applications and (ii) the formulation of new stochastic control models and algorithms that exploit statistical regularity in the disturbance process.The intellectual merit of the proposed research stems from the fact that it explicitly recognizes a new class of disturbances, human behavioral disturbances, seeking to develop an integrated approach to statistically characterizing and responding to future perturbations, adapting gracefully to uncertainty about the future. The anticipated research outcomes will be relevant in diverse fields, including stochastic hybrid control and human automation interaction.As a broader implication, the proposed research will enable the design of future field deployable artificial pancreas systems, potentially improving the lives of 1.5 million Americans suffering from Type 1 diabetes. With help from the two graduate students funded by the project, the principle investigator will supervise a ?Capstone? design course, exposing undergraduates to various aspects of control under human behavioral disturbances.

CPS：小：控制受人类行为干扰本研究的目的是开发一种综合的方法，控制系统设计的情况下，干扰主要是由于日常的人类行为，例如，在未来的人工胰腺系统的膳食和运动是影响血糖浓度的主要干扰。该方法是认识到，人类行为干扰（i）通常是随机的，但不能被视为零均值白色噪声过程和（ii）发生的统计规律，但不能被视为周期性的，由于人类行为的自然变化。这类新出现的问题需要（i）为特定应用推导新的扰动数学表示和（ii）制定新的随机控制模型和算法，利用扰动过程中的统计规律性。拟议研究的智力价值源于这样一个事实，即它明确地认识到一类新的扰动，人类行为扰动，寻求制定一种综合办法，对未来的扰动进行统计定性和应对，并适当地适应未来的不确定性。预期的研究成果将在不同的领域，包括随机混合控制和人类自动化交互。作为一个更广泛的含义，拟议的研究将使未来的现场部署人工胰腺系统的设计，可能改善150万美国人的生活患有1型糖尿病。在该项目资助的两名研究生的帮助下，主要研究人员将监督一个？顶点石？设计课程，让大学生接触人类行为干扰下的各个方面的控制。
