Talk:Control system
From Wikipedia, the free encyclopedia
Don't merge the articles.
Classic control theory, both analog and digital, is about measuring and optimizing stability and response of a physical motion or property like temperature, using transfer functions and disturbances and a whole array of other very effective mathematical tools. Within this theory, the word "system" is used to describe the entirety of nodes and should not be confused with "Control System"
Control Systems, as it is commonly used among engineers today describes the hardware and software designs within machines that aquire data, communicate, compute, and control motion or physical properties. Control theory may be used to design, program and optimize within this physical structure. The control system may be large (GPS controlled navigation) or very small within a PC board or even within a silicon chip.
The Control System article should reference the Control Theory article only (and vise versa). It currently tries to be both.

[edit] Control system + Control Theory? Not Quite...
I believe that it would be a mistake to merge the two articles. Control theory concentrates on the mathematical models. "Control System" concentrates on practical applicatiosn. Control theory often does not take into account some of the issues that are encountered by engineers in the petrochemical industry, mostly because "neat models" do not exist for those reactions.
Having been exposed to both the theory (in college, while studying for my electrical engineering degree) and application (in the petrochemical industry for eleven years), I believe that there is room enough on this Website to distinguish between theory and application.
I like the links at the bottom of the control system article that relate to the types of control systems that are used today.

[edit] untitled response
often less than $1 US
sorry but often is greatly exaggregated here, yes you can get controllers for below $1 but these are the exeption even in quantyties 10k+. check any supplier you like (atmel, microchip, renesas, any).
[edit] MERGE control engineering
As a control engineer myself, I think the Control engineering section covers most of what is covered here (and in fact most of the stuff I was thinking of adding to this page).
[edit] Regarding merger of control theory and control system
One can surly merge Control Theory and System but what but the sharp difference both have. Control Theory has Classical and Modern Version, while Control System has lot to deal with Hardware realization. System part should contain application oriented article, specifically how control is applied to varies application. On a litter side, Control System can fail while control theory will never fail.
[edit] I vote for the merge...
While I agree with Karen's comment about the need to differentiate between theory and system (practice), the way that "Control system" is presented here is more in line with theory than practice, although I too think the links at the end are appropriate. I would like to see the redundant theoretical content merged while keeping the two categories separate, and then expanding practical applications of the theory in the "Control system" heading.

[edit] Merge: Eliminate Redundancy
Just because control theory and control systems are not the same thing does not mean that they are nearly inseperable. Both articles would benefit from a merger, because of the inherent redundancy of defining and elaborating upon each topic. Control systems are the realization of control theory; explaining why and how the first works requires knowledge of and elaboration on the second.
- Not so. Many things have a 'control system' that does not depend on linear feedback, nor have the slightest connection with mathematical control theory. Examples include traffic lights (simple sequencing, that may alter due to traffic flow or lack of it), hydraulic presses (that may include an interlock to make sure that all safely guards are in place) and just about every other application of a sequencing PLC. These articles need room to diverge - not be joined at the hip. Sure, let's eliminate redundancy (and there's a lot more in PID controller too), but then let's extend what's left. --Nigelj 18:34, 5 October 2006 (UTC)
[edit] Don't merge them
They have to do with almost completely different things.

They are too diffrent!!!
Un-named
- Um. Although that's not a terribly cogent argument, as a former real-time control systems programmer and control theory garduate, I do agree that they are separate concepts and should be handled separately. Guy 12:24, 20 October 2006 (UTC)
