项目摘要

This U.S.-Italy award will support a long-term visit by Professor Peter Dorato of the University of New Mexico to the Politecnico di Torino to collaborate with Professor Roberto Tempo and others of that institution. The main focus of the research will be on the extension of the U.S. principal investigator's theory of U-parameter design for robust feed back systems to multi-variable systems and multi-objective design problems. The principal investigator's theory of U- parameter design is based on the parameterization of all robustly stabilizing compensators by an arbitrary bounded- real function, or matrix is the multivariable, when the plant perturbations are assumed to be unstructured perturbations, specified in the frequency domain. This fee parameter- function has been exploited to optimize system performance for the nominal plant, in the case of single-input-output systems. A major thrust of the proposed sabbatical research will be to extend these results to multivariable systems. A final area of proposed research will be the study of robust control for systems with both unstructured frequency-domain uncertainty and parameter uncertainty. The principal investigator has focused his research in the former area and the Italian investigator has focused his research in the latter area. It is expected that this research will provide further insight into the design of robust multivariable systems. This should provide design tools for the accurate control of complex systems in the presence of significant uncertainties in plant dynamics.

这项美国-意大利奖将支持新墨西哥大学的彼得·多拉托教授对都灵理工大学进行长期访问，与罗伯托·特普教授和该校的其他人员进行合作。研究的主要重点将是将美国首席研究员的u参数设计理论扩展到多变量系统和多目标设计问题。主要研究者的U参数设计理论是基于所有鲁棒稳定补偿器的参数化，由任意有界实函数，或矩阵是多变量，当目标扰动被假设为非结构化扰动，指定在频域。在单输入输出系统的情况下，这个费用参数函数被用来优化标称工厂的系统性能。拟议的休假研究的一个主要重点将是将这些结果扩展到多变量系统。建议研究的最后一个领域将是研究具有非结构化频域不确定性和参数不确定性的系统的鲁棒控制。首席研究员将他的研究重点放在前一个领域，意大利研究员将他的研究重点放在后一个领域。期望本研究能为稳健多变量系统的设计提供进一步的见解。这应该为在植物动力学中存在重大不确定性的复杂系统的精确控制提供设计工具。
