Importance of control systems

An internal control system helps to optimise resources and achieve more efficient financial and administrative management, improving productivity.

Control systems have an important quality: They allow to determine the deviation between what was planned and what was achieved and, as a consequence, to correct the actions for the achievement of the set objectives.

Control systems give us more free time, reduce dangerous jobs, produce higher output, reduce the cost of things, etc.

Present and future

The PLC originated in the late 1960s in the automotive industry in the US and was designed to replace relay logic systems. The company Phoenix contact is now developing a high performance control system Based on the PLC next Technology

James Clerk Maxwell

James Clerk Maxwell, a prominent Scottish physicist of the 19th century, left a lasting legacy in science and technology. Contributions: 1. Formulation of electromagnetic equations 2. Prediction of electromagnetic waves 3. Development of electromagnetic devices 4. Contribution to the understanding of gas physics 5. Contribution to control systems

WATER CLOCK OF KTESIBIOS IN ALEXANDRIA EGYPT

Ktesibios, an ancient Greek inventor in Alexandria during the III BC. Is recognized for creating the water clock and a prototype of the hydraulic organ. His water clock incorporated a sophisticated control system with floats and valves, enabling precise timekeeping over extended periods. Ktesibios's inventions significantly advanced timekeeping technology and engineering, laying the groundwork for automation and regulation. The water clock's played an essential role in ancient timekeeping. Ktesibios's innovative spirit exemplified the intellectual atmosphere of ancient Alexandria, influencing modern engineering and timekeeping practices.

Cornelius J. Drebbel

He was born in 1572 and died in 1633. This Dutch ingeneer was known for been one of the developers of measurement and control systems, optics and chemistry.His most important inventions were the first submarine, a convex lense microscope, the first control system and the mercury thermometer. Although he was one of the greatest ingeneers of his century, he lived his last years in poverty.

In mathematics he is chiefly remembered for Heron's Formula.

Heron of Alexandria was a Hellenistic engineer and mathematician who was prominent in Alexandria, in the Roman province of Egypt where he was an engineer.

Heron published a well-recognised description of a steam-powered device called "the Aeolipila", sometimes called the "Heron engine".

Some of his inventions were: Steam engine; Pneumatics, hydraulics and robotics; Optics and Mathematics.

H.U. Lansberg

Flour mill Control System

This control system was made very simply but very ingeniously at the same time. The cuantity of grain suministred to the wind mill depended on the wind and the hardness of the grain. Because of this, the system functioned in optim options, and the speed of the mill wasn't constat, because that wasn't the purpose. In resume, Lansperg invented a control system that controlled the grain depending on the wind and the state of the grain. This was a very important improvement for that times.

CENTRIFUGAL FLYBALL GOVERNOR OF JAMES WATT

In 1764, scotsman James Watt grew thoughtful as he tinkered with the machinery associated with his job as a steam engine technician. The main problem with those early steam engines, called Newcomen engines, was that they were terribly inefficient. In fairly short order, Watt made radical improvements to the early steam engines, boosting their efficiency and utility. Those improved Watt engines changed the world, leading to the Industrial Revolution in England, America, and beyond.
