Instrumentation and control engineering is a vital field of study offered at many universities worldwide at both the graduate and postgraduate levels. This discipline integrates principles from various branches of engineering, providing a comprehensive understanding of the design, analysis, and management of automated systems.
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.

[7] [8] A notable application of dynamic control was in the area of crewed flight. The Wright brothers made their first successful test flights on December 17, 1903, and were distinguished by their ability to control their flights for substantial periods (more so than the ability to produce lift from an airfoil, which was known). Continuous ...
Information technology general controls (ITGC) are controls that apply to all systems, components, processes, and data for a given organization or information technology (IT) environment. The objectives of ITGCs are to ensure the proper development and implementation of applications, as well as the integrity of programs, data files, and ...
Adaptive control is the control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. [ 1 ] [ 2 ] For example, as an aircraft flies, its mass will slowly decrease as a result of fuel consumption; a control law is needed that adapts itself to such changing conditions.
IT control objectives typically relate to assuring the confidentiality, integrity, and availability of data and the overall management of the IT function. IT controls are often described in two categories: IT general controls and IT application controls. ITGC includes controls over the hardware, system software, operational processes, access to ...
This was revised in 1980 with some rudimentary semantics (SDL-80). The semantics were refined in 1984 (SDL-84), the textual form was introduced for machine processing and data was introduced. In 1988, SDL-88 was released with a formal basis for the language: an abstract grammar as well as a concrete grammar and a full formal definition.
The usual objective of control theory is to control a system, often called the plant, so its output follows a desired control signal, called the reference, which may be a fixed or changing value. To do this a controller is designed, which monitors the output and compares it with the reference.
