Articles about control
PID is difficult? PID is easy?
PID for a fool?
*** What is PID? ***
There are many definitions of PID, but my intention here is PID as a control method.
PID is a method of control (not object) whose performance has been tested in the field. Though now there are so many other control methods that 'more sophisticated', PID method is not left, otherwise more users now.
Ever mentioned that PID control system was first implemented around the 1910s as the autopilot control systems on Elmer Sperry ships. Even it is said, especially for proportional control strategy was implemented in 2000 years ago in the days of ancient Babylonian and Greek that is used as a water level control system.
In an article, describes the first commercial PID module in the form of an analog electronic circuit made by Taylor Instruments company in 1939.
based on the survey: nearly 97% industry engaged in the process, continue to use PID control module as a base for controlling the process variables. (source Honeywell,2000)
PID control methods easily applied in various types of controllers.
Besides easy, PID is also very powerful if applied correctly.
PID is stands for (Proportional-Integral-Derivative). It's qquite daunting when viewed from the stands.
Too mathematical? may be wrong, maybe right. Do not worry, we'll discuss it more logically, not just mathematical.
PID control is actually a combination of the three types of control, ie proportional control, integral control and deferential control.
Then there is the question, whether the controls can be used separately? can be yes or may not, we will discuss it further later.
To learn more about PID, first we should know about the term LOOP (open-loop and closed-loop) complete with the term "reference", "error", and "output". We should also know the term "plant" and "controllers".
These terms will be discussed one by one in the next post.

nice article... ^_^
ReplyDeletePID is a simple control method, but it is an interesting method...
We must consider some requirement before use this control...
I ever used this control, but gave some bad response because of controller's requirements didn't meet the plant's characteristics...
But, don't be worry...
Because ~ EVERYTHING is still UNDER CONTROL ~
