Weighting Matrix Selection a good rule of thumb when selecting the weighting matrices Rxx (or Ru and R uu is to normalize

广东海洋大学：《自动控制原理》课程教学资源（教学内容）第一章 绪论 §1.3 反馈控制系统的类型

可控性最重要的含义,正如我们前2讲所讨论的那样,是能够确 保我们自由地进行反馈控制系统的设计。尤其是我们知道 反馈控制定理——当且仅当系统状态可控时,任意确定的闭环系 统可以通过状态反馈任意配置极点

Topic 8 16.31 Feedback Control State-Space Systems What are state-space models? Why should we use them? How are they related to the transfer functions used in classical control design and how do we develop a state- space model?

本书分成五章。第一章是仿真，讲述环境工程过程的仿真即过程建模及求解的方法，并介绍活性污泥过程、二沉池二维流态等模型的建模和求解过程。第二章是过程控制，讲述反馈控制系统的控制规律及自动化仪表，并介绍污水处理主要设施的自动控制方法。第三章是动态分析，讲述如何导出过程的传递函数，以及如何利用传递函数对环境工程的过程动态进行定性和定量的分析。第四章是人工智能，重点介绍神经网络、专家系统和模糊控制的理论及在环境工程仿真与控制中的应用。第五章是复杂控制系统，介绍串级、分程、比值、前馈、选择性和非线性控制系统，以及在环境工程过程控制中的应用
