U.S.-France Cooperative Research: Analysis and Synthesis of Nonlinear Time-Varying Control Systems

9910030Tee这项为期三年的美法电气和通信系统合作研究奖项涉及加州大学圣巴巴拉分校的Andrew R.Teel和Petar Kokotovic，以及格勒诺布尔自动化实验室的Antonio Loria。该项目得到了国家科学基金会和法国国家科学研究中心(CNRS)的支持，将促进为时变系统开发新的统一稳定性分析工具，并在无源方法之后进行稳健控制设计。特别是，研究人员将重点研究非线性非自治系统(NLTV)的跟踪控制和时变镇定的控制律。在理论研究的同时，研究人员将把新的定理应用于机电系统、欠驱动机械手和自动车辆的跟踪控制等特殊问题。该项目利用了美国和法国在非线性控制领域所用技术的互补专业知识。当未知参数在动力学中出现非线性时，他们的共同努力将促进对时变系统自适应控制的理解。

9910030TeelThis three-year award for U.S.-France cooperative research in electrical and communication systems involves Andrew R. Teel and Petar Kokotovic of the University of California, Santa Barbara, and Antonio Loria of the Laboratoire d'Automatique de Grenoble. The project, supported under a program of the National Science Foundation and the French National Center for Scientific Research (CNRS), will facilitate the development of new uniform stability analysis tools for time-varying systems and robust control design following a passivity approach. In particular the investigators will focus on control laws for tracking control and time-varying stabilization of nonlinear nonautonomous systems (NLTV). In parallel to their theoretical study, the investigators will apply the new theorems to particular problems such as tracking control of electromechanical systems, under actuated manipulators, and autonomous vehicles.The project takes advantage of U.S. and French complementary expertise in the techniques used in the field of nonlinear control. Their joint efforts will advance understanding of adaptive control of time-varying systems when the unknown parameters appear nonlinearly in the dynamics.
