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 called automatic control (such as cruise control for
regulating a car's speed). Multi-disciplinary in nature, control systems
engineering activities focus on implementation of control systems mainly derived
by mathematical modeling of systems of a diverse range.
