From answers.com:

A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems – a PID is the most commonly used feedback controller. A PID controller calculates an "error" value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize the error by adjusting the process control inputs. In the absence of knowledge of the underlying process, a PID controller is the optimal controller.[1] However, for best performance, the PID parameters used in the calculation must be tuned according to the nature of the system – while the design is generic, the parameters depend on the specific system.

The PID controller calculation (algorithm) involves three separate parameters, and is accordingly sometimes called three-term control: the proportional, the integral and derivative values, denoted P, I, and D. The proportional value determines the reaction to the current error, the integral value determines the reaction based on the sum of recent errors, and the derivative value determines the reaction based on the rate at which the error has been changing. The weighted sum of these three actions is used to adjust the process via a control element such as the position of a control valve or the power supply of a heating element. Heuristically, these values can be interpreted in terms of time: P depends on the present error, I on the accumulation of past errors, and D is a prediction of future errors, based on current rate of change.[2]

By tuning the three constants in the PID controller algorithm, the controller can provide control action designed for specific process requirements. The response of the controller can be described in terms of the responsiveness of the controller to an error, the degree to which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm for control does not guarantee optimal control of the system or system stability.

Some applications may require using only one or two modes to provide the appropriate system control. This is achieved by setting the gain of undesired control outputs to zero. A PID controller will be called a PI, PD, P or I controller in the absence of the respective control actions. PI controllers are fairly common, since derivative action is sensitive to measurement noise, whereas the absence of an integral value may prevent the system from reaching its target value due to the control action.

Note: Due to the diversity of the field of control theory and application, many naming conventions for the relevant variables are in common use.

yeah, that is a huge drawback to internetting versus face-to-face communication. There is no tonal inflection to tell when someone is sarcastic. To me, your initial remark seemed not only ignorant, but inflammatory...almost third-grader-like. Something like "oh yeah? Well you...you...you're a great big stupidhead!"
Also a bit nonsensical to pick out a single work and make a bizarre statement of derision without any qualifiers...it degraded your response from being funny in your head to ridiculous when typed out.
So yes, smilies can help avoid this by giving an idea of where you're going with a statement in terms of silly or serious.

Wowsers.

I do not know your personality, we've never met. There are many many people who frequent these boards, so I apologize for not analizing and documenting people's/your posts in order to come up with a personality profile.
All I could do was look at what you wrote. It seemed to me, perhaps mistakenly, that you didn't know what a pid controller was and was teasing about it... so i copy/paste the first description my search came upon. I was simply trying to help. I gave no double-speak or sarcasm, that all came from you alone.

And yes, thank you for speaking directly about what you were communicating in that last post, even if crude, because it was honest and couldn't be misinterpreted. The more this happens, the less flamewars we get.

Uh oh. Looks like it's time for another dose:


Seemed to have a calming effect the last time, and if it works again, I think every digital remote thermometer thread should start off with it!

Cheers!
