内容摘要第1章绪论
本童介绍自动控制的基础知识，包括自动控制的基本概念，控制理论的发展过程，自动控制系统的组成、基本控制方式、分类，对自动控制系统的基本要求，以及控制系统实例。
1.1自动控制的基本概念
1.1.1自动控制的定义
在众多的现代工程领域中，自动控制技术承担着十分重要的角色，不仅在工业、农业、航天、航空、医学、交通运输、日常生活等领域，而且在金融、商业、社会管理等领域，都得到了广泛应用。
自动控制就是在无人参与的情况下，利用控制装置使生产机械、设备或生产过程中出观的一些物理量或工作状态能够自动地按照预定的数值或规律变化。例如，工业生产中，对加路好汽包的改位和E力、制卷自动上卷、电机转速的控制等；军事工业中，对火炮跟踪、人造卫星姿态、雷达等的控制：日常生活中，对电冰箱、空调器、声控灯等的控制。对这些广泛应用的控制问题，它的基础就是自动控制理论，
1.1.2控制理论的发展过程
自动控制理论的发展过程大体可以分为三个阶段：经典控制理论阶段、现代控制理论阶段和智能控制理论阶段。
1.经典控制理论阶段
孕在中国古代，劳动人民就凭借生产实践中积累的丰富经验和对反馈概念的直观认识，发明了许多闪烁控制理论智慧火花的杰作。例如，我国北宋时代（公元1086~1089年）苏颂和幕公廉利用天衡装置制造的水运仅象台，放是一个按负反馈原理构成的闭环非线性自动控制系统。随着科学技术与工业生产的发展，到了17、18世纪，自动控制技术逐濒应用到现代工业中。1681年，法国物理学家、发明家巴本（D.Papin）发明了作为安全调节装置的蜗炉压力调节器。l765年，做国人普尔佐诺夫（L.Polzunov)发明了篇汽锅炉水位调
节器，1788年，英国人瓦特（J.Wan）发明了蒸汽机离心调速器，解决了蒸汽机的速度控制问题，这是真正以闭环控制思想实现的自动化设备，引起了人们对控制技术的重视，他发表的经典必文（论调速器）是采用数学方法对控制系统进行理论研究的起点，通常认为这是自动控制你为一门学科发属的开端。1932年，美国物理学家豪查能待（H.Nyoux）提......
