9350346 Dasgupta This PI intends to continue his work in the area of robust stability. Robust stability mainly concerns the design of controllers which are guaranteed not to go unstable, so long as the plant to be controlled is linear and its parameter are known to lie within some fixed but wide interval. Many theorems have already been proven demonstrating stability for parameter sets within certain kinds of interval; the PI will attempt to develop techniques to help evaluate known intervals of uncertainty, to help determine whether they actually meet the required criteria. In addition, he intends to investigate whether Lyapunov stability theory can be applied to systems with parametric uncertainty particular types of nonlinear feedback. The PI also intends to perform theoretical analysis of signed adaptive filters for signal processing, and of the properties of Hopfield networks. He intends to explore robust stability theory as an alternative to learning or adaptive methods in channel equalization. He also plans to apply discrete event models to the modeling of cell growth. *** v s t tability mainly concerns the d $ $ ( F / S S / 1 Courier Symbol & Arial 5 Courier New S " h e e ( S R:\WW20USER\ABSTRACT.DOT Abstract Alicia E.

9350346 Dasgupta 该 PI 打算继续其在鲁棒稳定性领域的工作。 鲁棒稳定性主要涉及控制器的设计，只要被控制的对象是线性的并且已知其参数位于某个固定但较宽的区间内，控制器就保证不会变得不稳定。 许多定理已经被证明证明了参数集在某种区间内的稳定性； PI 将尝试开发技术来帮助评估已知的不确定性区间，以帮助确定它们是否确实满足所需的标准。 此外，他打算研究李亚普诺夫稳定性理论是否可以应用于具有参数不确定性的系统（特定类型的非线性反馈）。 PI 还打算对用于信号处理的带符号自适应滤波器以及 Hopfield 网络的特性进行理论分析。 他打算探索鲁棒稳定性理论作为通道均衡中学习或自适应方法的替代方法。 他还计划将离散事件模型应用于细胞生长建模。 *** v s t 稳定性主要涉及 d $$ ( F / S S / 1 Courier Symbol & Arial 5 Courier New S " he e ( S R:\WW20USER\ABSTRACT.DOT Abstract Alicia E.
