Research Initiation Award: Synthesis of Practically Implementable Robust Controllers

在过去的十年中，鲁棒控制器的设计取得了重大进展，产生了复杂的设计理论和算法，可以在存在不确定性的情况下产生高性能控制器，并使设计人员能够探测控制系统配置性能的基本限制。然而，理论设计问题忽略了一些重要的实现问题和约束，因此鲁棒控制设计目前倾向于用于研究性能限制，而不是实际生产控制器。所提出的研究是围绕在鲁棒控制器设计理论中纳入一般实现约束和要求的思想。一个例子是具有连续时间性能目标的采样数据控制器的设计，这源于对采样数据控制器的考虑。具有实现约束的控制器设计是一些具有理论挑战性的问题，这些问题的解决将大大提高鲁棒控制理论在控制实践中的适用性。＊＊＊

9309123 Bamieh The design of robust controllers has progressed significantly in the past decade, resulting in sophisticated design theories and algorithms that produce high performance controllers in the presence of uncertainty, and enabling the designer to probe the fundamental limits of performance of control systems configurations. However, theoretical design problems ignore some important implementations issues and constraints, and thus robust control designs tend to be currently used for investigating limits of performance rather than actually producing the controllers. The proposed research is centered around the idea of incorporating general implementation constraints and requirements in the theory of robust controller design. An example is the design of sampled-data controllers with continuous-time performance objectives, which arise from the consideration that sampled-data controllers. Controller design with implementation constraints give rise to theoretically challenging problems, and their solution will greatly enhance the applicability of robust control theory to control practice. ***
