RIMI: Reduction of Parameter Uncertainty and a New Approachto Robust Analysis and Design of Controllers

9353189 Olbrot拟议的研究将探讨参数不确定性模型的系统的鲁棒控制。 该研究将考虑的不确定参数属于一个已知的公差范围，并将攻击的问题，如何减少这个区域的基础上的知识，噪声测量。 新的算法将被开发用于测试的鲁棒性，可以处理减少参数的不确定性区域的非线性不等式的参数将是一个重要的困难。 参数不确定性的减少区域的确定将有助于使用已知的鲁棒控制设计。 研究将扩展时变鲁棒控制器的两种具体设计方法，即广义保持函数和切换无差拍控制器，并包括不确定参数和时滞的连续体。***

9353189 Olbrot The proposed research will investigate robust control for systems with parametric uncertainty models. The research will consider that the uncertain parameters belong to a known region of tolerances and will attack the problem of how to reduce this region based on a knowledge of noisy measurements. New algorithms will be developed for testing robustness which can handle the reduced parameter uncertainty regions where nonlinear inequalities for the parameters will be an essential difficulty. The determination of the reduced region of parameter uncertainty will facilitate the use of known robust control designs. The investigation will develop extensions of two specific design methods for time-varying robust controllers, generalized hold functions and switching dead beat controllers and include the continuum of uncertain parameters and time delays. ***
