The Maxwell electromagnetic field equations, discovered by J.C. Maxwell wrote a paper in the year 1868 "On Governors," that was able to explaining the exhibited by the fly ball governor. To be able to explain the control system, he made use of differential equations. This paper demonstrated the importance and helpfulness of mathematical models and methods in relation to comprehending complex phenomena. It also signaled the beginning of systems theory and mathematical control. Previous elements of control theory had appeared earlier by not as dramatically and as convincingly as in Maxwell's study.
Within the following one hundred years control theory made huge strides. New developments in mathematical methods made it feasible to more precisely control considerably more dynamic systems as opposed to the first fly ball governor. These updated techniques comprise various developments in optimal control during the 1950s and 1960s, followed by development in robust, stochastic, optimal and adaptive control methods during the 1970s and the 1980s.
New technology and applications of control methodology has helped make cleaner engines, with cleaner and more efficient processes helped make communication satellites and even traveling in space possible.
In the beginning, control engineering was practiced as just a part of mechanical engineering. Control theories were initially studied with electrical engineering since electrical circuits can simply be explained with control theory methods. At present, control engineering has emerged as a unique discipline.
The very first control partnerships had a current output that was represented with a voltage control input. For the reason that the right technology to be able to implement electrical control systems was unavailable then, designers left with the choice of slow responding mechanical systems and less efficient systems. The governor is a very efficient mechanical controller which is still usually used by several hydro plants. In the long run, process control systems became available before modern power electronics. These process controls systems were often used in industrial applications and were devised by mechanical engineers utilizing hydraulic and pneumatic control devices, many of which are still being used nowadays.
Hydraulics
The hydraulics are the "muscles" of the forklift. 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 components include: heavy-duty hydraulic valves, leak resistant O-ring face seal fittings, long lasting tilt and hoist cylinders, and fine micron filters. The control valve has been strategically positioned in order to prolong component life by minimizing exposure to heat sources.
The Yale forklift could withstand the most extreme working situations coming out on top with their great reliability. These machinery have been built in such a precise way that attention to detail has been considered so as to keep the operator as comfortable as they can be.
