Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. [1] Meanwhile, control engineering , also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors.
The resulting plots are analyzed as for other control charts, using the rules that are deemed appropriate for the process and the desired level of control. At the least, any points above either upper control limits or below the lower control limit are marked and considered a signal of changes in the underlying process that are worth further ...
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
Control systems play a critical role in space flight.. Control engineering, also known as control systems engineering and, in some European countries, automation engineering, is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments.

A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. ... Measurements from the real world ...
A control loop using a discrete controller. Field signals are flow rate measurement from the sensor, and control output to the valve. A valve positioner ensures correct valve operation. The simplest control systems are based around small discrete controllers with a single control loop each. These are usually panel mounted which allows direct ...
In an elementary school system, the hours a teacher works or the gain in knowledge demonstrated by the students on a national examination are examples of characteristics that may be selected for measurement, or control. The second element of control, the sensor, is a means for measuring the characteristic. For example, in a home heating system ...
Control engineering – 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.
