Forklift Control Valve

Forklift Control Valve

around the web

Forklift Control Valve - Automatic control systems were initially created more than two thousand years ago. The ancient water clock of Ktesibios in Alexandria Egypt dating to the third century B.C. is believed to be the very first feedback control equipment on record. This particular clock kept time by regulating the water level inside a vessel and the water flow from the vessel. A popular style, this successful tool was being made in the same way in Baghdad when the Mongols captured the city in 1258 A.D.

Through history, different automatic devices have been utilized in order to accomplish specific tasks or to simply entertain. A popular European design all through the 17th and 18th centuries was the automata. This device was an example of "open-loop" control, featuring dancing figures that will repeat the same job repeatedly.

Closed loop or feedback controlled machines consist of the temperature regulator common on furnaces. This was actually developed in the year 1620 and attributed to Drebbel. One more example is the centrifugal fly ball governor developed during 1788 by James Watt and utilized for regulating steam engine speed.

The Maxwell electromagnetic field equations, discovered by J.C. Maxwell wrote a paper in 1868 "On Governors," that was able to explaining the exhibited by the fly ball governor. To be able to explain the control system, he utilized differential equations. This paper demonstrated the importance and helpfulness of mathematical models and methods in relation to comprehending complex phenomena. It also signaled the start of systems theory and mathematical control. Previous elements of control theory had appeared earlier by not as convincingly and as dramatically as in Maxwell's analysis.

Within the next one hundred years control theory made huge strides. New developments in mathematical techniques made it possible to more accurately control considerably more dynamic systems as opposed to the first fly ball governor. These updated methods include different developments in optimal control during the 1950s and 1960s, followed by development in stochastic, robust, adaptive and optimal control techniques in the 1970s and the 1980s.

New technology and applications of control methodology has helped produce cleaner engines, with cleaner and more efficient methods helped make communication satellites and even traveling in space possible.

Initially, control engineering was practiced as a part of mechanical engineering. Additionally, control theory was firstly studied as part of electrical engineering in view of the fact that electrical circuits can often be simply described with control theory techniques. Now, control engineering has emerged as a unique discipline.

The very first control relationships had a current output that was represented with a voltage control input. As the correct technology in order to implement electrical control systems was unavailable at that moment, designers left with the choice of slow responding mechanical systems and less efficient systems. The governor is a really efficient mechanical controller that is still normally used by several hydro plants. Eventually, process control systems became accessible prior to modern power electronics. These process controls systems were often utilized in industrial applications and were devised by mechanical engineers utilizing hydraulic and pneumatic control equipments, a lot of which are still being utilized at present.
