普拉巴卡尔河Pagilla，俄克拉荷马州州立大学9982071职业生涯：鲁棒控制器的大规模互联系统：Web处理系统的应用大规模互联系统出现在各种工程应用，如大型结构，电力系统和制造过程。用于幅材处理线的幅材处理系统是具有大量控制和测量变量的大规模互连动态系统的真实示例。幅材是呈连续柔性条形式的任何材料，其与其宽度相比非常长，与其厚度相比非常宽。例如纸张、织物、胶带、照相胶片和金属条。本文的研究重点是大规模互联系统的建模与鲁棒控制，并将其应用于纸幅处理系统。将为卷筒纸和卷筒纸处理系统的基本元件，如卷筒纸和卷筒纸输送机，开发精确的动态模型。基于这些模型的鲁棒分散控制器将开发。将研究在幅材加工过程中的重要实际问题，如由于辊的不对准和不适当地卷绕辊的干扰，并设计鲁棒控制方案来拒绝这些类型的干扰。研究活动与教育计划紧密结合，通过设备的共同使用，并将研究问题纳入本科和研究生课程。该教育计划包括远程学习活动，如通过双向压缩视频教学课程和为实践工程师开发短期课程。所提出的工作对提高连续幅材生产线的性能具有重要影响。理论发展的重点是大系统的基本问题和一般控制结构，因此它将与其他应用有关。拟议的远程学习活动和短期课程准备将为实习工程师提供方便的大学课程。

Prabhakar R. Pagilla, Oklahoma State University9982071CAREER: Robust Controllers for Large-Scale Interconnected Systems: Applications to Web Handling SystemsLarge-scale interconnected systems appear in a variety of engineering applications such as large structures, power systems and manufacturing processes. Web handling systems for web processing lines are true examples of large-scale interconnected dynamic systems with a large number of control and measurement variables. A web is any material in continuous flexible strip form which is very long compared to its width and very wide compared to its thickness. Examples include paper, fabrics, adhesive tape, photographic film and strip metals. Modeling and robust control of large-scale interconnected systems with applications to web handling systems is the focus of this research. Accurate dynamic models for the web and the basic elements of web handling systems, such as accumulators and dancers, will be developed. Based on these models robust decentralized controllers will be developed. Significant practical problems in web processes such as disturbances due to misalignment of rollers and improperly wound rolls will be studied, and robust control schemes to reject these type of disturbances will be designed. Research activities are integrated closely with education plans through common usage of equipment and bringing research problems into undergraduate and graduate curriculum. The education plan includes distance learning activities such as teaching courses via two-way-compressed-video and developing short courses for practicing engineers. The proposed work has significant impact on improving the performance of continuous web process lines. The theory development focuses on fundamental issues and general control structures for large-scale systems and hence it will be relevant to other applications. The proposed distance learning activities and short course preparation will provide practicing engineers to get easy access to university courses.
