否则这是不可能的。尽管机械化一词通常用于指机器简单地替代人类劳动，但自动化通常意味着将机器集成到一个自治系统中。在这个阶段，理解这两个术语在技术上下文中的某些意义上的差异非常重要，特别是在本课程中。下文给出了这些信息。1.自动化系统可能包括控制系统，但反过来并非如此。控制系统可以是自动化系统的一部分。2.控制系统的主要功能是确保输出符合设定值。然而，自动化系统可能具有更多的功能，例如计算控制系统的设定值、监控系统性能、工厂启动或关闭、作业和设备调度等hat would otherwise be impossible. Although the term mechanization is often used to refer to the simple replacement of human labour by machines, automation generally implies the integration of machines into a selfgoverning system.It is important at this stage to understand some of the differences in the senses that these two terms are generally interpreted in technical contexts and specifically in this course. These are given below. 1. Automation Systems may include Control Systems but the reverse is not true. Control Systems may be parts of Automation Systems. 2. The main function of control systems is to ensure that outputs follow the set points. However, Automation Systems may have much more functionality, such as computing set points for control systems, monitoring system performance, plant startup or shutdown, job and equipment scheduling etc. Automation Systems are essential for most modern industries
