控制系统有几种分类方法
控制系统有几种分类方法
1、按控制原理的不同，自动控制系统分为开环控制系统和闭环控制系统。
开环控制系统
在开环控制系统中，系统输出只受输入的控制，控制精度和抑制干扰的特性都比较差。开环控制系统中，基于按时序进行逻辑控制的称为顺序控制系统；由顺序控制装置、检测元件、执行机构和被控工业对象所组成。主要应用于机械、化工、物料装卸运输等过程的控制以及机械手和生产自动线。
闭环控制系统
闭环控制系统是建立在反馈原理基础之上的，利用输出量同期望值的偏差对系统进行控制，可获得比较好的控制性能。闭环控制系统又称反馈控制系统。
2、按给定信号分类，自动控制系统可分为恒值控制系统、随动控制系统和程序控制系统。
恒值控制系统
给定值不变，要求系统输出量以一定的精度接近给定希望值的系统。如生产过程中的温度、压力、流量、液位高度、电动机转速等自动控制系统属于恒值系统。
