Synopsis
《计算机控制技术及应用》通过总结作者的科研成果和吸收国内外的先进理论、方法和技术，以计算机控制系统的网络化、开放化、智能化和集成化发展趋势为主线索，主要介绍计算机控制系统的基本概念和计算机控制系统的典型形式，计算机控制系统的数学描述与基本分析方法，以及数字PID控制器、最少拍控制系统、达林算法、状态变量设计法等设计方法及其各种改进算法。重点突出计算机控制系统输入输出通道接口的设计方法和典型控制系统的设计案例与实现方法等。《计算机控制技术及应用》注重运用CDIO工程教育理念，立足培养实际动手能力、综合应用能力、创新思维能力。每章均附有精选的习题。《计算机控制技术及应用》配有免费电子课件，欢迎选用《计算机控制技术及应用》作教材的老师登录索取。《计算机控制技术及应用》可作为普通高等院校控制科学类、电子信息类、电气工程类、仪器仪表类、机械电子类及其相关专业的本科生、研究生及教师的教科书和教学参考书，也可作为广大科技工作者和工程技术人员的参考书。不同类型的两部分是由A／D和D／A连接，以保证信息的畅通。图2-2所示的系统若从A-B两端向下看，（包括A／D，计算机，D／A）可以看成一个连续部分。而从A'-B'两端向上看，则可将A／D、被控对象、D／A等效为一个离散系统。由于这两种不同理解，因此在设计方法上就可以分为模拟化设计方法和离散化设计方法。由此可见，计算机控制系统的描述方法可分为：一是将连续的被控对象离散化，等效为一个离散系统数学模型，然后在离散系统的范畴内分析整个闭环系统；二是将数字控制器等效为一个连续环节，然后采用连续系统的方法来分析与设计整个控制系统。一般来说，前一种方法使用较为普遍。本章即根据前一种方法，介绍计算机控制系统数学描述的建立过程。至于后一种方法可参考连续系统控制理论的建立过程。从严格意义上讲，离散控制、采样控制、数字控制的含义并不完全相同。离散控制处理的是离散信号，采样控制处理的是采样信号，数字控制处理的是数字信号。所谓离散控制是指系统中有一处或几处信号是一串脉冲信号或数码，这些信号仅在离散瞬时上有值，这样的系统称为离散系统。把控制系统中的离散信号是脉冲序列形式的离散系统，称为采样控制系统或脉冲控制系统。而把那些幅值被整量化的离散信号或数字序列形式的离散系统称为数字控制系统或计算机控制系统。2.2信号的采样与保持前面已经讲过，计算机系统要把连续变化的量变成离散量后再进行处理。因此，计算机系统被称为离散系统，亦称采样数据系统。这种离散系统与连续系统的区别仅仅在于离散系统的信号是以采样数据为主要形式，而连续系统则是连续信号。2.2.1信号的分类模拟控制处理的是连续信号，它是连续时间变量t的函数，除个别间断点外，这些信号的波形是光滑的曲线，如图2-3a所示。这一类信号称为模拟信号（analogsignal），大多数客观存在的信号都是属于这一类信号。还有一类信号（如电报信号等），显然它的时间取值是连续的，但它的幅度却只限于有限个数值，这一类信号称为量化信号（quantizedsignal），如图2.3b所示。以上两类信号都是连续时间信号。离散时间信号（简称离散信号，discretesignal）则与连续时间信号
