Career in Control Systems Control systems are another
area of electrical engineering where circuit analysis is used. A control
system is designed to regulate the behavior of one or more variables in
some desired manner. Control systems play major roles in our everyday
life. Household appliances such as heating and air-conditioning systems,
switch-controlled thermostats, washers and dryers, cruise controllers
in automobiles, elevators, traffic lights, manufacturing plants, navigation
systems—all utilize control systems. In the aerospace field, precision
guidance of space probes, the wide range of operational modes of the space
shuttle, and the ability to maneuver space vehicles remotely from earth
all require knowledge of control systems. In the manufacturing sector,
repetitive production line operations are increasingly performed by robots,
which are programmable control systems designed to operate for many hours
without fatigue. Control engineering integrates circuit theory and communication theory.
It is not limited to any specific engineering discipline but may involve
environmental, chemical, aeronautical, mechanical, civil, and electrical
engineering. For example, a typical task for a control system engineer
might be to design a speed regulator for a disk drive head. A thorough understanding of control systems techniques is essential to
the electrical engineer and is of great value for designing control systems
to perform the desired task. |
