自动控制原理英文教材，难度稍大，适合有一定基础的人阅读。

本书是自动控制领域的专著，是作者结合20多年来的主要成果及教学经验历时十多年完成的，主要阐述应用微分几何理论设计非线性控制系统的方法。全书共两卷，这是第二卷。第二卷的章节排列与卷相衔接，从0章开始到4章为止，重点介绍非线性系统的设计方法，主要关注存在模型不确定性情况下实现全局或任意大区域内稳定性的问题。体例延续卷，与卷没有明显重叠。0章阐述将输入-状态稳定性概念运用于互联系统稳定性分析的一些概念和方法，并说明耗散性概念如何用于互联系统的稳定性分析；1章介绍如何把递推综合Lyapunov函数法应用于鲁棒全局渐近镇定方法；2章介绍实现任意大区域内的稳定性的鲁棒半全局渐近镇定方法；3章讨论对有有限增益的系统如何借助小增益定理实现鲁棒稳定；4章引入嵌套饱和函数的反馈律设计方法，介绍如何借助其幅值不超过一固定界的状态反馈律达到全局渐近稳定。

This book introduces the fundamental concepts necessary for designing, using, and implementing database systems and database applications.
