Operator

Definition

⏹The technology of

☐controlling a series of events to transform a material into a desired end product is called process control.控制技术的一系列事件把资料达到所希望的最终产品,被称为过程控制

⏹Short examples:

☐M aking of fire for cooking rice (primitive and modern)The fly-ball governor for steam engine control (1774)短的例子:让火煮米饭(原始的和现代)州长的fly-ball蒸汽发动机控制(1774)

⏹Tendency of industrial process control

☐being computerized,

☐being automatized , and

☐being instrumented w ith smart sensors and M EM S

工业过程控制的趋势

在计算机化,

在潜意识中自动使用,

被装备智能传感器和微机电系统(M EM S)

A Few Examples

1.Flow Control in Oil refinery Plant:

Do w e run around the plant to adjust the valves w hen required?流量控制,是炼油厂植物:

我们到处跑植物调节阀门在需要的时候吗?
