Control engineering
Control engineering or control
systems engineering is the engineering discipline
that applies control
theory to design systems with desired behaviors. The practice
uses sensors to
measure the output performance of the device being controlled and those
measurements can be used to give feedback to the
input actuators that
can make corrections toward desired performance. When a device is designed to perform
without the need of human inputs for correction it is calledautomatic control (such
as cruise
control for regulating the speed of a car). Multi-discipilinary in
nature,control sytem enginering on impelementation of control sytems mainly
derived by mathematical modeling of sytems of a diverse range .
Automatic control systems
were first developed over two thousand years ago. The first feedback control
device on record is thought to be the ancient Ktesibios's water clock inAlexandria, Egypt around
the third century B.C. It kept time by regulating the water level in a vessel
and, therefore, the water flow from that vessel. This certainly was a
successful device as water clocks of similar design were still being made in
Baghdad when the Mongols captured the
city in 1258 A.D. A variety of automatic devices have been used over the
centuries to accomplish useful tasks or simply to just entertain. The latter
includes the automata, popular in Europe in the 17th and 18th centuries,
featuring dancing figures that would repeat the same task over and over again;
these automata are examples of open-loop control. Milestones among feedback, or
"closed-loop" automatic control devices, include the temperature
regulator of a furnace attributed to Drebbel, circa 1620, and the centrifugal
flyball governor used for regulating the speed of steam engines by James Watt
in 1788
In his 1868 paper
"On Governors", James Clerk Maxwell was
able to explain instabilities exhibited by the flyball governor using differential
equations to describe the control system. This demonstrated the importance and
usefulness of mathematical models and methods in understanding complex
phenomena, and signaled the beginning of mathematical control and systems
theory. Elements of control theory had appeared earlier but not as dramatically
and convincingly as in Maxwell's analysis.
Matrix methods are
significantly limited for MIMO systems where linear independence cannot be
assured in the relationship between inputs and outputs. Being fairly new,
modern control theory has many areas yet to be explored. Scholars like Rudolf E. Kalman and Aleksandr Lyapunov are
well-known among the people who have shaped modern control theory.
Control engineering
is the engineering discipline that
focuses on the modeling of
a diverse range of dynamic
systems (e.g. mechanical systems) and the design of controllers that
will cause these systems to behave in the desired manner. Although such
controllers need not be electrical many are and hence control engineering is
often viewed as a subfield of electrical engineering. However, the falling
price of microprocessors is making the actual implementation of a control
system essentially trivial[citation needed].
As a result, focus is shifting back to the mechanical and process engineering
discipline, as intimate knowledge of the physical system being controlled is
often desired.
