9410897 Saberi Almost every physical system has maximum and minimum limits or otherwise called saturation on its control signal or actuator. The task of designing feedback laws for linear systems with saturating inputs is very complex and challenging. Perhaps due to this complexity, the effect of saturation of actuators has been ignored in most of the modern control literature. This proposal seeks to develop both the analysis and design tools for systems with saturating actuators. Our initial work shows that a semi-global framework is a natural and desirable framework for the design of such systems. Our recent effort also indicates the emergence of powerful techniques for designing systems with saturating actuators. This proposal focuses on some of the central and fundamental control problems for systems with saturating actuators. Among the many problems which must be confronted are: robust semi- global stabilization, robust semi-global disturbance rejection and semi-global output regulation and tracking. ***

9410897 Saberi几乎每个物理系统都具有最大和最小限制，或者在其控制信号或执行器上称为饱和。 使用饱和输入的线性系统设计反馈定律的任务非常复杂且具有挑战性。 也许由于这种复杂性，在大多数现代控制文献中，执行器饱和的效果被忽略了。 该建议旨在为具有饱和执行器的系统开发分析和设计工具。 我们的最初工作表明，半全球框架是用于设计此类系统的自然而理想的框架。 我们最近的努力还表明了用饱和执行器设计系统的强大技术的出现。 该提案重点介绍了具有饱和执行器的系统的一些中心和基本控制问题。 在许多必须面临的问题中，有：强大的半全球稳定，鲁棒的半全球干扰排斥和半全球输出调节和跟踪。 ***
