9502034 Teel The research objective of this proposal is to further the understanding of the dynamics and control of highly nonlinear systems. The mathematical methods emphasized will be those that seek to characterize nonlinear systems in terms of their input- output behavior. This viewpoint is flexible and can accommodate real world uncertainties and complicated nonlinear behavior. Recent breakthroughs regarding control of systems with hard limits on the magnitude and permissible rates of control signals have developed by taking this view. Part of the research plan is to show that the algorithms which have been developed for the control saturation problem are applicable to a wide variety of problems. The significance of the control algorithms will be enhanced by investigating optimization strategies and rapprochement with more standard control algorithms. Indeed, these algorithms may provide a link between standard control and more recent "intelligent" control. The second part of the research plan seeks to develop both conceptual insight into and computational algorithms for nonlinear control by taking a general input-output point of view. It is believed that this will lead to results analogous to many fundamental results that are known for linear systems: a parameterization of stabilizing compensators, optimization over such parameters, simultaneous stabilization, etc. Software development will be a means of transporting the research developments of this proposal to the industrial sector. The educational objective of this research is to facilitate a learning environment which is tailored to the unique aspects of today's engineering student. The premise is that today's students are very different from those that preceded them, with regard to perspectives, values and expectation. Accordingly, changes in teaching styles and perspectives must be investigated. The educational plan calls for critical self-and outside- examination of teachin g styles and methods. Partially, this will occur within the structure of a faculty development program at the University. In addition, the plan calls for a thorough re- examination of laboratory teaching methods, especially in the subfield of control. A consideration of visualization techniques as a teaching tool is emphasized. Finally, a teaching approach that motivates the student through the history of and vision for electrical engineering and control is recommended. In this regard, mentoring is seen to be a crucial part of the education process. ***

小行星9502034 本研究的目的是进一步了解高度非线性系统的动力学和控制。 强调的数学方法将是那些试图描述非线性系统的输入-输出行为。 这种观点是灵活的，可以容纳真实的世界的不确定性和复杂的非线性行为。 最近的突破，关于控制系统的控制与硬限制的幅度和允许的速率的控制信号已经采取这种观点。 研究计划的一部分是表明，已开发的控制饱和问题的算法适用于各种各样的问题。 通过研究优化策略和与更多标准控制算法的和解，将增强控制算法的重要性。 事实上，这些算法可以提供标准控制和更近的“智能”控制之间的联系。 研究计划的第二部分旨在通过一般的输入输出观点来发展非线性控制的概念见解和计算算法。 据信，这将导致与线性系统已知的许多基本结果类似的结果：稳定补偿器的参数化、此类参数的优化、同时稳定等。软件开发将成为将该提案的研究进展转移到工业部门的一种手段。 这项研究的教育目标是促进学习环境，这是针对今天的工程专业学生的独特方面。 前提是，今天的学生与以前的学生在观点、价值观和期望方面有很大不同。 因此，必须研究教学风格和观点的变化。 教育计划要求对教学风格和方法进行批判性的自我和外部检查。 部分，这将发生在大学教师发展计划的结构。 此外，该计划要求彻底重新审查实验室教学方法，特别是在控制子领域。 强调了可视化技术作为教学工具的考虑。 最后，推荐了一种通过电气工程和控制的历史和愿景来激励学生的教学方法。 在这方面，辅导被视为教育过程的一个关键部分。 ***
