The Maxwell electromagnetic field equations, discovered by J.C. Maxwell wrote a paper in the year 1868 "On Governors," which was able to describing the exhibited by the fly ball governor. In order to describe the control system, he made use of differential equations. This paper demonstrated the usefulness and importance of mathematical methods and models in relation to understanding complicated phenomena. It likewise signaled the start of mathematical control and systems theory. Previous elements of control theory had appeared before by not as dramatically and as convincingly as in Maxwell's study.
Within the following 100 years control theory made huge strides. New developments in mathematical techniques made it feasible to more accurately control considerably more dynamic systems than the original fly ball governor. These updated techniques consist of various developments in optimal control in the 1950s and 1960s, followed by development in stochastic, robust, optimal and adaptive control methods during 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.
Primarily, control engineering was practiced as a part of mechanical engineering. As well, control theory was firstly studied as part of electrical engineering since electrical circuits can often be simply described with control theory techniques. Nowadays, control engineering has emerged as a unique discipline.
The very first controls had current outputs represented with a voltage control input. In order to implement electrical control systems, the correct technology was unavailable at that time, the designers were left with less efficient systems and the choice of slow responding mechanical systems. The governor is a very effective mechanical controller that is still normally utilized by some hydro plants. In the long run, process control systems became available prior to modern power electronics. These process controls systems were normally used in industrial applications and were devised by mechanical engineers making use of hydraulic and pneumatic control equipments, many of which are still being utilized at present.
Hydraulics
The hydraulics are the forklift's "muscles". They provide the necessary force needed to lift heavy loads during the entirety of a long shift. All Yale trucks feature industrial grade hydraulic components. Some of these parts include: heavy-duty hydraulic valves, leak resistant O-ring face seal fittings, long lasting hoist and tilt cylinders, and fine micron filters. The control valve has been strategically placed in order to prolong component life by reducing exposure to heat sources.
Yale's diesel forklifts provide extreme reliability and are recognized for withstanding harsh working conditions and coming out on top. These machinery have been constructed in such a precise manner that attention to detail has been considered so as to keep the operator as comfortable as they could be.
